Discover why ALTER is a dominant force in Wordle. Using five of the most powerful letters in the English language, ALTER consistently slashes the dictionary and sets up easy solves.
Secures A and E, the two most important vowels, though it sacrifices I, O, and U.
Tests L, T, and R—three absolute powerhouse consonants that form the backbone of English.
The -ER ending is incredibly common. Landing it on turn one immediately identifies the word shape.
Our analysis relies on empirical data to explain why ALTER stands out among the elite Wordle starting words.
We test ALTER against all 2,309 possible Wordle solutions to observe its candidate elimination rates.
We measure the immense value of checking A, L, T, E, and R on turn one.
We determine how effectively the common -ER ending frames the remaining puzzle possibilities.
We calculate its mathematical information gain. ALTER scores an elite 4.02 bits of entropy.
We determine how many possible answers remain on average after playing ALTER (~82 words).
We combine these metrics to generate a final grade of 94/100.
If you’ve ever watched Wheel of Fortune, you know that R, S, T, L, N, and E are given to players in the final round because they are the most common letters in English. ALTER uses five of those six letters. It is an absolute powerhouse.
ALTER provides highly actionable feedback. If you hit greens on E and R, you are immediately funneled into the extremely common -ER ending (like WATER or PAPER). The presence of A gives you a central vowel, while L and T check for common consonant blends (like BL-, CL-, -LT).
While ALTER is mathematically elite, it competes closely with its anagrams, LATER and ALERT. Words that test S instead of R or L (like SLATE or STARE) often rank slightly higher in algorithmic models due to how S interacts with the dictionary, but ALTER remains a phenomenal choice that is easy for humans to play.
Let’s examine how each of ALTER’s letters contributes to its overall effectiveness.
Frequency: High
Positional Strength: Strong
A is a common starting letter for Wordle answers (e.g., ALIEN, ABOUT, APPLE). Nailing a green A here sets a very strong frame.
Frequency: High
Positional Strength: Strong
L is incredibly common in position 2 as part of consonant blends like BL-, CL-, FL-, GL-, PL-, and SL-.
Frequency: Very High
Positional Strength: Moderate
T is a massive structural asset. While position 3 isn’t its most common spot (positions 1 and 4 are better), testing it early is always good.
Frequency: Highest
Positional Strength: Very Strong
E in position 4 is a critical check for -ER and -EL endings.
Frequency: Very High
Positional Strength: Ultimate
R is extremely common in position 5. The -ER suffix is one of the most populous groups in the Wordle dictionary.
ALTER uses A and E. While it sacrifices the broader vowel coverage of words like AUDIO or ADIEU, A and E are statistically the two most critical vowels to locate. Missing them immediately points you toward O, I, and U.
L, T, and R. These are three of the most powerful consonants in Wordle. They form the skeleton of thousands of English words (e.g., T-R-, -L-T, -L-R). Securing them early gives you a massive advantage in word construction.
To understand ALTER’s strength, we look at Information Theory.
How does ALTER compare to the modern heavyweights of the Wordle dictionary?
Winner: LATER (Slightly)
All three are anagrams. LATER is often considered the mathematically superior arrangement because L is slightly better in position 1, and A is better in position 2. However, the difference in entropy is negligible (hundredths of a point). Play the one that feels most intuitive to you.
Winner: SLATE
SLATE is mathematically dominant (Entropy 4.29). It uses only two vowels (A, E) but captures S, L, and T. SLATE provides slightly better candidate reduction than ALTER because S divides the dictionary better than R.
Winner: Tie
STARE shares A, T, E, R with ALTER, but swaps L for S. Both are phenomenally strong. STARE gets the edge in pure math (testing S), while ALTER is slightly better at avoiding Hard Mode traps.
Winner: RAISE
RAISE tests an extra vowel (I) and the letter S. It is generally considered a safer, more balanced opener for human players, though ALTER’s consonant heavy approach provides a sharper frame when it hits.
Winner: Tie
TRACE is an incredible consonant-heavy option (T, R, C). ALTER swaps C for L. L and C are very close in utility, making this a pure preference choice.
Winner: CRANE
CRANE gives excellent C and N coverage and was famously recommended by 3Blue1Brown. It generally provides a smoother transition into guess two than ALTER.
ALTER performs solidly in Hard Mode (Rating: 84/100). The biggest risk is hitting the -TER trap. If you get a green T, E, and R, you might be stuck guessing CATER, WATER, MATER, PATER, HATER, LATER, or EATER one by one, which can cost you your streak.
How to interpret feedback states after playing ALTER:
Meaning: You have hit the common -TER ending. The answer is likely WATER, CATER, or HATER. Best next move: In normal mode, guess CHAWK or MACHO to test C, H, W, M simultaneously. Common mistakes: Guessing them one by one in Hard Mode.
Meaning: L is present but not in position 2. Look for words starting with L (e.g., LUNCH, LOGIC). Best next move: LIONS or LUNCH. Common mistakes: Testing L in position 5 right away, as words ending in L usually have A or E (which you know are gray).
Meaning: A, L, T, E, and R are absent. The word heavily relies on O, U, I, S, N, C. Best next move: SOUND or SCION. Common mistakes: Guessing another A/E word out of habit.
Yes, it is phenomenal. It checks five of the most common letters in English (A, L, T, E, R).
It uses the famous ‘Wheel of Fortune’ letters. Humans naturally gravitate toward R, S, T, L, N, E.
They are incredibly similar anagrams. LATER is technically slightly better mathematically, but ALTER is just as effective for human play.
Again, they are anagrams. They perform almost identically. Choose the one that is easiest for you to build words from.
They are very close. RAISE has better vowel coverage (A, I, E) and checks S, while ALTER has better consonant coverage (L, T, R).
It is solid, but you must be careful of the -TER trap. If you hit T, E, R, you might get stuck in a long guessing sequence (CATER, WATER, etc.).
If ALTER is entirely gray, guess SOUND, SNOOP, or SCION to test S, O, U, I, N, C.
Yes! ALTER is on the official Wordle answer list, meaning you have a 1 in 2,309 chance of winning on turn one.
STARE is generally considered slightly better because it checks S instead of L, which provides better structural information. STARE is also an answer list word.
SLATE is widely considered the best practical Wordle opener. It outperforms ALTER mathematically because S divides the dictionary better than R.
WordleBot recognizes ALTER as a very strong word, usually assigning it a high skill score (94+).
ALTER has an elite entropy score of 4.02 bits, meaning it eliminates over 95% of the dictionary on an average guess.
Absolutely. It uses letters everyone knows are common, and the resulting patterns are easy to solve.
An all-gray ALTER means the word likely relies on O, U, I, S, N, C. Guess SOUND or SNOB.
Yes, ALTER is vastly superior to ADIEU. ADIEU wastes slots on too many vowels; ALTER perfectly balances vowels with top-tier consonants.
Yes. AUDIO is mathematically very weak. ALTER provides significantly better candidate reduction.
It means the word ends in E. Look for common patterns like -CE, -NE, -PE, or -SE on your second guess.
On average, ALTER reduces the 2,309 possible words down to roughly 82 remaining candidates.
Hitting the _ _ T E R trap (e.g., WATER, CATER, MATER) in Hard Mode can sometimes lead to a losing guessing game.
If you care purely about minimizing your average guess count mathematically, yes. SALET is the absolute best. But ALTER is an actual answer.
They are tied in practical utility. TRACE is better for C hunters, while ALTER checks the L.
If E is gray, consider if the word ends in Y. ALTER eliminates E, making Y the next most likely ending.
Yes, meaning to change or cause to change in character or composition.
Yes, it is excellent for multi-board games because of its broad consonant coverage.
Very frequently, largely due to the high probability of E ending the word.
Candidate reduction measures how many words are eliminated from the 2,309 possible answers. ALTER is very strong in this metric (82 remaining).
CRANE tests C and N, while ALTER tests L and T. CRANE is slightly favored by algorithms, but both are elite.
None. Every single letter in ALTER is in the top 10 most frequent letters in English.
L is one of the most common consonant blend letters (BL, CL, FL, GL, PL, SL), making it highly structural.
