1. No name of two letters came as three
To define it, no, not to count its number

2. And in its heart is a verb and letter both
Each has a role in it by limiting its extent

3. It is matched by a name specially endowed with prolongation
Distinguishing it from all else by its extension

4. So marvel at it being a name while it is a verb that has certainly been devoid
And a letter and meaning whose likeness is its reciprocity
