Thus defined, zero derivation is less transparent than other derivational processes like affixation.
The rule "A, DuE/TBEE/TBEA/TBSA/TBSE" asserts that a noun (A) cannot be followed by any of the morphemes in DuE category (Grammatical Category, Verb), TBEE (derivational suffixes which derive verbs from verbs), TBEA (derivational suffixes which derive nouns from verbs), TBSA (derivational suffixes which derive noun from adjectives) or TBSE (derivational suffixes which derive adjectives from verbs).
The changing and heterogeneous nature of the language at this period is especially reflected in derivational patterns.
Borrowed SL technical terms derived from common linguistic roots can assimilate, with varying degrees, to the TL inflectional and derivational systems.
Other factors also need to be considered, such as the frequencies of the stem, inflection and derivational affix and whether the spoken and written forms of the stems and affixes are easily recognizable.
We have devised a methodology that consists of the following steps: (i) the retrieval of all records of strong verbs from the lexical database of Old English Nerthus (www.nerthusproject.com); (6) (ii) the identification of all inflectional forms of strong verbs relevant for derivational morphology; (iii) the isolation of basic strong verbs; (iv) the compilation of derivational paradigms; (v) the identification of the vocalic contrasts holding in derivation; (vi) the classification of the contrasts based on ablaut; and (vii) the distinction of phonologically motivated alternations from instances of allomorphic variation.

In addition, the current evidence focuses on Dutch and English, Germanic languages with a very different morphology from Spanish, whose derivational morphology is particularly rich.
In addition to the ongoing phonological and morphosyntactic shifts that mark the transition from medieval to modern Spanish, this period also witnessed enrichment of the Spanish lexicon through the incorporation of numerous neologisms in the form of lexical and semantic borrowings from living and dead languages with which Spanish was in contact, as well as through the coining of new words by means of its various derivational resources.
The formative vari is also found in Turkish where it appears as a derivational suffix that attaches to nouns to derive adjectives.
Each of the four cases illustrated above follows a strikingly similar pattern of lexicalization, taking full advantage of Italian's highly productive derivational morphologyo The lexicalist hypothesis puts forth the assumption that word formation (and therefore derivational) rules are integrated in the lexicon, capturing most closely the process of suffixation (Booij 1977; Scalise 1980).
