Etymology
From false:, from  fals:, from  falsus:, perfect passive participle of fallo:. Uncommon before the 12 century, the word was reinforced in Middle English by fals: (cf.  faus:). Displaced native Middle English les:, from Old English leas:; more at leasing:.

For spelling, the -e (on -lse) is so the end is pronounced /ls/, rather than /lz/ as in falls:, and does not change the vowel (‘a’). Compare else:, pulse:, convulse:.
