EL
Worth 2 points before any premium square, and the lowest-scoring of the 96 — tied with 35 others.
EL extends into 14 three-letter words, which is the 19th most extendable of 96 — tied with 10 others. That is the number worth memorising: a two-letter word is a place to put tiles, but a well-hooked one is a place to put them where the board stays open.
Every hook
- B→BEL
- C→CEL
- D→DEL
- E→EEL
- G→GEL
- M→MEL
- S→SEL
- T→TEL
- D→ELD
- F→ELF
- K→ELK
- L→ELL
- M→ELM
- S→ELS
Not all of them are equally reachable, which a bare count of 14 hides. EL hooks on 11 distinct letters, and the ones you are likeliest to be holding are E (60% of opening racks), T (36% of opening racks) and D (26% of opening racks). The rarest is K, at 7%.
How often you can actually play it
Out of an opening rack, 14.18% of the time you hold the letters for EL outright, the 21st likeliest of 96 — tied with 3 others. Counting a blank as whichever letter is missing lifts that to 21.86%, though spending one of the two blanks on a two-letter word is rarely the play. Exact hypergeometrics over the 100-tile bag, not a simulation.
