Macroparadigm

In morphology, a macroparadigm is a notion which is introduced in Carstairs (1987) to refer to a collection of paradigms which are distinct in phonologically, morphosyntactically or semantically predictable ways.

Example
Compare the following three Hungarian verbal paradigms:

stem	olvas	 'read' ül	'sit'  mond	 'say' 1 sg. olvas-ok	ül-ök	 	mond-ok 2 sg. olvas-ol	ül-sz	 	mond-asz 3 sg. olvas		ül		mond 1 pl.	olvas-unk	ül-ünk 		mond-unk 2 pl.	olvas-tok	ül-tök 		mond-otok 3 pl.	olvas-nak	ül-nek	 	mond-anak ('s' = [s], 'sz' = [s])

Carstairs assumes that these three verbs belong to the same macroparadigm, since the variation is fully predictable. First, stems with back vowels (olvas, mond) select back vowel suffixes (-ok, -unk), while verb stems with front vowels select front vowels. This variation is due to a rule of vowel harmony. Second, if a consonant cluster of three members arises this is split up by an epenthetic vowel. Third, in the 2sg. form a stem ending in a sibilant takes the suffix -ol/-el, while other stems take -sz (or a variant).
