What does "is for" mean exactly? [closed]

Solution 1:

They actually are similar. In both cases a letter is used to "stand in for" (that is, to represent) a word that begins with that letter (L for Look, A for Apple).

So I think a single-word substitute would be "represents". But that's not as concise or poetic.

Here's a song along those lines:
