The set of arguments that a verb can appear with is referred to as sub categorization frame.
Lexical Semantics: study of how meanings of individual words are combined into the meaning of sentences.
Hypernymy vs Hyponymy
animal is a hypernym of cat
cat is a hyponym of animal
Antonym – words with opposite meanings
Meronymy – part belonging to a whole
tire is a meronym of a car
Holonym – whole corresponding to a part
Synonyms – words with similar meanings
Homonyms – words that are spelled the same but have different meanings
bank – river bank; bank – a financial institution
Senses Polyseme – if the different senses (meanings) of the word are related. Example “branch” could mean part of a tree; could mean dependant part of an organization.
Ambiguity – lexical ambiguity refers to both homonymy and polyseme
Homophony – homonyms that are also pronounced the same. “bass” for example could mean a fish or low pitched sound – and is NOT a homophone.
