Ameliorative development of the meaning is the improvement of the connotational component of meaning, e.g. ‘minister’ originally denoted ‘a servant, an attendant’, but now – ‘a civil servant of higher rank, a person administering a department of state’.
Polysemy is the linguistic phenomenon when a word has more than one meaning, resulting in semantic structure consisting of a number of lexico-semantic variants.
Lexico-semantic variant of the word is every meaning of a polysemantic word with reference to what it denotes in the extra-linguistic world (referential meaning) and with respect to the other meanings with which it is contrasted in the semantic structure (differential meaning).
Homonyms are words identical in sound-form or spelling but different in meaning.
Cases of full homonymy are generally observed in words belonging to the same part of speech, where we observe the coincidences in their paradigms, e .g. ‘a seal¹ (n.)’ and ‘a seal² (n.)’.
