5-Letter Words Ending in ER: Lists and Patterns
434 five-letter words end in ER in the 12,478-word verified English word set — 3.48% of the full dataset. The ER ending fixes two positions simultaneously: E in position 4 and R in position 5.
Once tile evidence confirms both, the candidate pool compresses from 12,478 to 434 in a single constraint application. This guide covers the full ER-ending subset, position-3 letter patterns, and how to apply the ER constraint in Wordle and Scrabble.
This guide is for Wordle players who have confirmed E in position 4 and R in position 5 and need to filter the 434-word ER pool, and for Scrabble players identifying ER-ending words from partial rack information.
Source: 12,478-word verified English word set
ER-ending words: 434 (3.48% of dataset)
No-repeat ER words: 287 (66.1% of ER subset)
Constraint: Position 4 = E AND Position 5 = R
Filter now: → Word Finder — set position 4 to E, position 5 to R
434 five-letter words end in ER — 3.48% of the 12,478-word verified English word set. 287 carry no repeated letters (66.1%), slightly above the full dataset average. The ER constraint fixes positions 4 and 5 simultaneously — a highly restrictive positional constraint that compresses 12,478 candidates to 434 in a single filter application. → Filter ER words at the Word Finder
How Many 5-Letter Words End in ER?
434 five-letter words end in ER in the 12,478-word verified English word set — 3.48% of the full word pool. This places ER among the more common two-letter endings in the dataset, alongside patterns such as -ED, -LY, and -ES.
The 66.1% no-repeat rate within the ER subset is slightly above the full dataset's 64.2% baseline. ER-ending words tend toward unique-letter forms because the E-R ending already occupies two distinct letters, leaving three remaining positions that naturally favour varied consonants. Words where E or R is repeated in positions 1–3 exist — ENTER (E repeated), ERROR (R and O repeated) — but are proportionally fewer than in the full dataset.
ER as a Positional Constraint — What Two Fixed Positions Mean
The ER ending fixes two positions simultaneously: E must occupy position 4 and R must occupy position 5. Few adjacent two-position constraints reduce the candidate pool this aggressively — the E-R combination is particularly effective because both letters are high-frequency in English, producing a well-populated 434-word pool rather than the sparse results that low-frequency letter pairs generate.
Each additional constraint compresses the pool further. Apply combined filters at the Word Finder.
The two-position fix is what makes ER confirmation so valuable in late-game Wordle. A yellow E (confirmed but not in position 4) combined with a yellow R (confirmed but not in position 5) does not justify filtering to the ER-ending pool — the ER suffix is not yet confirmed. Only two green tiles at positions 4 and 5 definitively restrict the candidate space to the 434-word ER pool. → See tile identification signals below.
Position-3 Letter Patterns in ER-Ending Words
With positions 4 and 5 fixed as E and R, the three remaining variable positions (1, 2, 3) determine which ER words are available for any given tile state. Position 3 — the letter immediately before ER — shows the clearest pattern clustering, as certain consonants produce large families of ER words.
| Position 3 Letter | Sub-pattern | Example Words | No-Repeat Examples |
|---|---|---|---|
| K | _?KER | BAKER, FAKER, JOKER, MAKER, POKER, TAKER | All no-repeat — K not repeated in AK/OK/IK patterns |
| V | _?VER | COVER, DIVER, FEVER, GIVER, LIVER, MOVER, RIVER | Mostly no-repeat — V appears once only |
| T | _?TER | AFTER, INTER, LITER, MITER, OUTER, VOTER, WATER | High no-repeat — T rarely repeats in TER endings |
| W | _?WER | BOWER, LOWER, MOWER, POWER, SOWER, TOWER | All no-repeat — W is low-frequency and never repeats in this pattern |
| N | _?NER | DINER, LINER, MINER, OWNER, TUNER | Mostly no-repeat |
| L | _?LER | FILER, OILER, RULER, TILER | All no-repeat — L appears once |
| P | _?PER | CAPER, HYPER, PAPER, SUPER, TAPER, UPPER | Mixed — UPPER (P and P), PAPER (P repeated) reduce no-repeat count |
| G | _?GER | ANGER, EAGER, LAGER, TIGER, WAGER | Mostly no-repeat |
K, V, and W in position 3 produce the cleanest no-repeat ER sub-patterns — these sub-patterns strongly favour no-repeat constructions because K, V, and W rarely appear elsewhere in the same five-letter word alongside E and R. The P-E-R pattern is the most likely source of repeated-letter ER words (UPPER, PAPER) because P frequently appears in positions 1–2 as well as position 3.

How to Identify ER-Ending Words From Wordle Tile Signals
The ER ending is confirmed only when both E and R return green tiles in their respective positions. Yellow tiles for either letter indicate the letter is present in the answer but not in position 4 (E) or position 5 (R) — the ER ending is not yet confirmed in that case.
→ Answer definitively ends in ER → filter to 434-word pool
→ Does NOT end in ER → R is somewhere in positions 1–4
→ ER ending possible, not confirmed → wait for positional confirmation
ER Words in Scrabble — Cross-Game Utility
The ER ending has moderate Scrabble utility. E carries 1 point and R carries 1 point — the suffix itself adds only 2 points to any word's base score. ER-ending Scrabble value is therefore driven almost entirely by the letters in positions 1–3.
| ER Word | Scrabble Base Score | High-Value Letters | Wordle Compatible |
|---|---|---|---|
| JOKER | 14 pts | J(8) + K(5) — high-value opening positions | Yes |
| BOXER | 14 pts | B(3) + X(8) — X doubles the value | Yes |
| HYPER | 13 pts | H(4) + Y(4) — two mid-value tiles | Yes |
| FAKER | 12 pts | F(4) + K(5) | Yes |
| VIPER | 10 pts | V(4) + P(3) | Yes |
| WATER | 8 pts | W(4) — low-value suffix letters drag score | Yes |
| LINER | 5 pts | All common tiles — low base score | Yes |
For Scrabble, prioritise ER words where positions 1–3 include J, X, Q, Z, K, or F. The ER suffix is efficient for rack clearance when common tiles need placing — but for score maximisation, an ER word without a high-value consonant in positions 1–3 will rarely exceed 8–10 base points.
