This journal article deals with Old English word-formation as represented by a derivational map. In a derivational map, lexical derivation applies gradually, so that a process only occurs at a time and affixes are attached one by one. This theoretical and methodological stance holds good for most derivations but there is also evidence of non-gradual formations with the prefixes ǣ-, ge-, or-, twi-, ðri-, and un-. After discussing the relevant derivatives with each of the aforementioned affixes, the conclusions are reached that non-gradual formations arise in frequent word-formation patterns; they constitute, with few exceptions, an adjectival phenomenon; and they are mainly associated with secondary derivational functions. Regarding the derivational map of Old English, the conclusion is drawn that non-gradual formations have to be represented by means of reconstructed forms so that each node represents one lexeme and each edge marks one morphological process.Key words: Derivational map, Old English, gradual derivation, graph theory.
IntRoductIon. the deRIvAtIonAL mAp of oLd engLIshWhile the study of the derivational morphology of Old English has been focused on the typological changes relating to the rise of word-formation from stem-formation (Kastovsky 2006) and the growing importance of analytic tendencies (Haselow 2011), Martín Arista (2008, 2009, 2010a, 2011a, 2011b, 2011c, 2012a, 2012b, 2013 has put forward a model of derivational morphology based on the structural-functional theory of language called Role and Reference Grammar (Van Valin and LaPolla 1997;Van Valin 2005) and applied it to Old English. Among other results of this research programme, the lexical derivation of Old English has been described in terms of variation, so that different lexical layers comprising various word-formation processes coexist and interact (Martín Arista 2011b). An exhaustive description has also been proposed of the derivational processes of zero derivation, affixation and compounding of Old English that relies on the information provided by the lexical database of Old English Nerthus (www.nerthusproject.com), which is in turn based on the data provided by the dictionaries of Bosworth-Toller, Clark Hall and Sweet. The lexical database Nerthus offers not only an extensive description of the lexicon but also a principled explanation for this linguistic component based on hierarchy (prime vs. non-prime) and inheritance (exponent of paradigm vs. non-exponent of paradigm). For instance, in the derivational paradigm of the strong verb (class IIIb) ābelgan 'to make angry', this verb is the lexical prime, to which all the members (non-primes) of the lexical paradigm are directly or indirectly related, both for semantic and morphological reasons. That is, a relationship of semantic and morphological inheritance holds between the verb ābelgan on the one hand and the nouns ābylg 'anger', ābylgnes 'offence' and ābylgð 'anger', on the other. Moreover, the noun ābylg is the base of derivation of the suffixed nouns ābylgnes and ...
