The Non- Finite Forms
The non- Finite forms are: the infinitive and the two Participles. The non- finite forms in OE are more loosely connected with the finite system than in Modern English, for two reasons:

1. 
   there are no analytic forms in OE, although their prototypes exist as various combinations of link-verb and predicative; 2) the non- finite forms themselves possess fewer verbal features. Their subsequent development binds them more closely with the finite verb. Still since every OE verb can form verbals (non- finite forms), we must consider these as part of the verb paradigm.

      The Infinitive. There are two infinitive forms; one of them is called the Dative Infinitive (the Indo- European infinitive had been a declinable noun). This infinitive is mainly used to denote purpose, but it is quite safe to say that it generally function as an independent member of the sentence: it could function as subject and predicative. The infinitive with the ending -an functioned, as a rule, in combination with preterite- present verbs and in other verbal collocations. The second infinitive is preceded by “to” and has the ending “anne”; it is used in independent syntactic positions, mainly as adverbial modifier of purpose, but also as subject and predicative.
