What is the meaning of the prefix ir

in-, il-, im-, ir- The prefix in- changes its form to il- before an l; to im- before b, m or p; and to ir- before r. This prefix (and its variations) have two meanings. Meaning 1: not, without.

covert: hidden or secret

candid: truthful and straightforward

what i get from these phrases is covert means undercover or underground and that's where the flower is in april. on the other hand, may is the month where flowers start to bloom and thats the reason why candid is being used as a word to describe the blossoming period of a flower.

hope this answer you.
