Why SI words matter

Words containing SI are handy for Scrabble, Words with Friends and word puzzles — filter the list above by length to find the play you need.

A quick statistical tour

A few numbers before you scroll: the 7102 words here run from 2 to 15 letters, with 10-letter words the largest group (1068 entries). Wordle players have 98 five-letter options, and there are 636 seven-letter candidates for a Scrabble bingo. The single best scorer is OVEREMPHASIZING at 35 points before multipliers.

For quick reference, the top of the score table reads: OVEREMPHASIZING (35), PHOTOSYNTHESIZE (35), PSYCHOPHYSICIST (35), ZYGAPOPHYSIS (35), HYPOTHESIZING (34). The longest entry is ACCESSIBILITIES at 15 letters, and the average word here is worth about 15 points. If you are fishing for these words, keep I (7102 appearances), S (7102) and E (4861) on your rack.

Three easy picks from this list

SIN — a 3-letter, 3-point play that slots into tight board lanes where longer words won't fit.
Playing SIR across a double-word square turns its base 3 points into 6 — solid value for 3 tiles.
SIS — 3 letters for 3 points; every tile in it is a common draw, so it shows up rack after rack.

Once those stick, file away the next tier too: SIT (3), NISI (4), SIAL (4), SILL (4), SILO (4).

One chunk, many words: SI

If you are studying English, SI is a high-leverage chunk: instead of memorising each word cold, anchor the SI pattern and let the surrounding letters vary. Word-game players get a parallel benefit — when a crossword grid or a Wordle guess reveals the SI sequence, this page is the complete candidate pool, already sorted by Scrabble value.
