Some notes on strong verbs and related issues

The situation in Indo-European

Example Present Preterit singular Preterit plural Past participle
Class 1-3 ride, freeze, sing, help e o ø ø
Class 4 bear e o e: ø
Class 5 give e o e: e
Class 6 take a o o: a
Class 7 fall reduplication

Zeroing in on Classes 1-3

The distinction among some of the verb classes in Indo-European is anachronistic. In particular, at that stage, there is no need to distinguish among Classes 1-3, since the relevant verb all formed their principal parts according to the same pattern (e, o, ø, ø).

Verb class Example IE Gmc OE GVS
1 ride ei, oi, i i:, ai, i i:, a:, i i:, o:, i ai, o:, i
2 freeze eu, ou, u eu, au, o eo:, e:a, o e:, o:, o i:, o:, o
3a sing eN, oN, N iN, aN, uN
3b help eL, oL, L eL, aL, oL

The decline of principal parts

Old English and early Middle English verbs had four principal parts:

The distinction between the two preterit forms continues to the present day with be: singular was vs. plural were. But with all other verbs, the preterit sg. and preterit pl. collapsed in the course of Middle English.

The southern development is thus analogous to the case of regular verbs in that there is no surface distinction between the simple preterit and the past participle.
