This word consists of three morphemes.
This word is consisted of three morphemes.
Which one is correct?
How can I use the passive form?
In which example?
The argument is this:
Comprise means 'to consist of', 'to be composed of'.
The word consists of three morphemes. The word is composed of three morphemes. BUT. The word comprises three morphemes.
Not The word is comprised of three morphemes.
'Comprise' already comprises the 'of' component.
It's similar to 'contain'. If a word contains three morphemes, we don't say it's contained of three morphemes (yet).
See here for a brief discussion (under the 'usage' section).
comprise - Definition from the Merriam-Webster Online Dictionary
However, the battle for this word by purists is probably lost, given the tone of this entry.
Thank you Raymott
So, I'll never see "is consisted of".
