About ER
ER is the sound someone makes while searching for the next word. In play it is a quiet, safe two-letter word that can sit next to an E or an R already on the board.

ER scores 2 points
Before any bonus squares: E 1 + R 1 = 2. On a double-word square that's 4, on a triple-word 6, and every letter bonus under one of these tiles is applied first.
Example: ER as the first play
Later in the game, put the E on a 3L square and ER is worth 4 before any word bonus.
Hooks: one tile makes a new word
After ER (6):
Place that one tile so it also forms a word in the other direction and both words score.
