Irregular verbs: sellan – solde – sold; tellan – tolde – told;
Preterite-present verbs: were preserved, their forms underwent changes due to the general tendencies of the period
Conjugation: uderwent considerable changes: as a result of levelling of unstressed vowels the difference between the endings –an, -on- and –en was lost. The final – n, which characterized many verb forms, was lost. It proved stable only in some second participles, where it has been preserved down to the MnE period. But there were dialectal varieties in the verb endings. An example of conjugation (weak verb haven) 1 have, 2 hast 3 hath Pl. Han Past 1 hadde 2 haddest 3 hadde pl. hadden); to be (ben) 1 am 2 art 3 is pl.: ben Past: was, were, was; pl.: weren.
The Perfect: Perfect forms, which arose in OE, are widely used in ME. In Chaucer’s works there are many sentences with the Present Perfect and the Past Perfect forms of intransitive verbs were derived by means of the verb (ben) be.
The Continuous: In ME there appeared first instances of a continuous aspect, consisting of the verb be and the first particple. They were very rare. The origin is not quite clear. Ilyish gives the following explanation: he is on huntinge: the preposition ‘on’ became weakened and turned into a prefix ‘a-‘: he is a-hunting: then the prefix was dropped and the verbal substantive ‘huntinge’ became a participle. Perfect continuous forms are quite rare in ME.
Future Tense: A special future form, which started in OE, became in ME a regular part of the tense system. Chaucer uses this form in many cases. Occasionally, however, the future meaning may be accompanied by some modal shade.
Moods: The Subjunctive mood preserved in ME many features it had in OE. An unreal condition referring to the present is expressed by the phrase ‘wolde + infinitive; if the action refers to the past the phrase ‘wolde + perfect infinitive is used.
