An equative construction is a grammatical construction using an adjective or an adverb in the comparative of equality (also called "equative degree"). An equative construction equates a comparee with a standard in terms of a certain quality or action. In English, such a construction takes the form “as X as S”, where S is the standard.
In modern French, the equative construction takes the form “aussi X que S”.
Welsh has an equative degree of adjectives, usually indicated by the suffix -ed; for example, "hyned" (â ...)", meaning "as old (as ...)".
In older French, equative constructions had the standard marker comme (aussi grande comme moi), but this was later replaced by que.
Welsh has an equative degree of the adjective, meaning 'as big', 'as new', and so on. It often has an air of exclamation about it: 'how big!', 'how new!' The equative suffix is -ed.
