Week 3 - Toolkit for Describing Language

3. The study of the internal structure of words.
6. The different categories or parts of speech to which words belong (e.g. nouns, verbs, adjectives).
9. Words that refer to aspects of human existence in the world (e.g. book, girl, class).
10. Words that do not have clear lexical meaning, but have a purely grammatical function (e.g. articles, prepositions).
12. The smallest unit of linguistic meaning or function.
13. Natural groupings of a sentence, displayed as syntactic units in a phrase structure tree.
14. When a word, phrase, or sentence has multiple meanings.

1. Affixes that may possibly, but not necessarily, form a different word or change the word class.
2. Single morpheme that represents the core of the word - the basic meaning that remains when all affixes are stripped from the word.
4. A sentence with the same meaning (same truth conditions) as another.
5. Morphemes that never constitute words by themselves, but must always attach to other morphemes (e.g. prefixes, suffixes).
7. 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.
8. Single morphemes that constitute words on their own.
11. Formed when a root is combined with an affix.
