The /m/ sound is spelled with <m>, <mm> or <mb> in comb. The /l/ sound is spelled with <l> or <ll>. Notice how the homograph lead pairs with Med and mead. The software picked out numerous pairs in which the sounds appeared in reverse order such as lame/male, smile/slime and lemon/melon, but I have disallowed then as they are not strictly minimal, though confusable.
This is a contrast between a bilabial nasal continuant and a lateral continuant, both voiced. It is not a problem.
Several pairs are formed from a Latinate -ium ending contrasting with its adjective derivative such as bacterium/bacterial. Other interesting pairs include:
amass alas
foreman fallen
magician logician
marvel larval
meagrely legally
measure leisure
Mexican lexicon
mobster lobster
moral laurel
pemmican pelican
sesame Cecily
summon sullen
woman woollen
