Week 3 - Toolkit for Describing Language

2. The different categories or parts of speech to which words belong (e.g. nouns, verbs, adjectives).
6. Single morpheme that represents the core of the word - the basic meaning that remains when all affixes are stripped from the word.
7. Natural groupings of a sentence, displayed as syntactic units in a phrase structure tree.
8. The study of the internal structure of words.
12. The smallest unit of linguistic meaning or function.
13. Words that do not have clear lexical meaning, but have a purely grammatical function (e.g. articles, prepositions).
14. A sentence with the same meaning (same truth conditions) as another.

1. Morphemes that never constitute words by themselves, but must always attach to other morphemes (e.g. prefixes, suffixes).
3. When a word, phrase, or sentence has multiple meanings.
4. Single morphemes that constitute words on their own.
5. Words that refer to aspects of human existence in the world (e.g. book, girl, class).
9. Formed when a root is combined with an affix.
10. Affixes that may possibly, but not necessarily, form a different word or change the word class.
11. Bound grammatical morphemes that are attached to a word according to rules of syntax. They leave a word in the same word class, but add extra grammatical info.
