nondecomposability? How many morphemes are in that word.

I have five-non,de,ability,com,ity

what about the pos?

Please re-think this.

http://en.wikipedia.org/wiki/Morpheme

I got: non, de, compose, able, ity. Is that correct?

What is entailment in semantics? List three words (not necessarily related to each other) that evidence entailment and say what meanings each word entails.

Can you explain the 3 words part of this question. Three random words?

I got: non, de, compose, able, ity. Is that correct?

This is correct, I think, since "compose" can be a word on its own. If you learn it's not correct, though, separate the root (pos) from the prefix (com).

For your other question, please go to http://www.google.com and enter entailment semantics

If com and pos can be separated just like able and ity, shouldn't I separate them now? I know com is a prefix but I didn't know pos is a root.

-pon- is the root of the Latin word meaning "to place" -- pono, ponere, posui, positum.

See the 3rd entry down for a good explanation of the etymology of "compose" in its parts. But since it has a complete meaning as "compose," I don't think you'd have to take it apart for morpheme identification. (For phoneme identification, that would be different!)

To determine the number of morphemes in the word "nondecomposability," we first need to break it down into its individual morphemes. A morpheme is the smallest unit of meaning in a word.

Let's break it down:

1. "Non" is a prefix that means "not" or "the opposite of."
2. "De" is another prefix that means "un" or "remove from."
3. "Com" is a prefix that means "with" or "together."
4. "Pos" is not a separate morpheme in this word. It is actually part of the root word "compose," which means "to put together" or "to create."
5. "Ability" is a noun suffix that means "the state or quality of being able to."
6. "Ity" is a noun suffix that signifies a quality or state.

Based on this breakdown, there are six morphemes in the word "nondecomposability": non-, de-, com-, pos-, -ability, and -ity.
