Comprise [THINK: consist (I)]

Compose [THINK: form (O)]

 

“The fundamental difference between comprise and compose has to do with the whole versus the parts of any object or concept.

…comprise is a verb that means “to include or contain” or “to consist of” as in The pie comprises 8 slices.

…Compose means “to be or constitute a part of element of” or “to make up or form the basis of,” as in Eight slices compose the pie.

…The key rule to remember is that the whole comprises the elements or parts, and the elements or parts compose the whole.“
