Strategy for this list

S is worth 1 in Scrabble and starts ~13,000 words — the largest slice of the dictionary. S is the game's single most valuable tile because it pluralises almost anything and hooks onto virtually every common noun and verb. S-openers with premium potential include SEIZED, SIZZLE, SIZE. In Wordle, S is common in position 1 and position 5 (SHORE, HORES); an S in either position is a strong information-gathering test.
