The /m/ sound is spelled with <m> or <mm>. The /r/ sound is spelled with <r> or <rr>. Notice how the homograph read makes pairs with mead and Med.
This is a contrast between a bilabial nasal continuant and a retroflex continuant, both voiced and only occurring initially or medially. It is not a problem.
Since /r/ does not occur finally, several verb pairs only appear in the -ing form when an /r/ link is introduced, such as charming/charring. Other interesting pairs include:
imitate irritate
meagrely regally
mental rental
mummy rummy
muscle rustle
