Reconstruction talk:Proto-Germanic/þekwōną

þekwōną
May I suggest that the cited form, þekwōną, is a late form, and that in PGmc there was a distinction between the transitive (causative) verb and the intransitive verb:


 * þekwāną –   weak verb 3  – intransitive  – to become thick


 * þikwijaną – weak verb 1 –  transitive   –  to make thick

… and that this distinction was lost when both verbs merged as *þekwōną at a later stage in PGmc or PWGmc, > OE þiccian.

In defence of this proposition, I will point out that OE þiccian is shown in Bosworth-Toller as transitive (to make thick) and intransitive (to become thick); and that there is a tendency for weak verbs of other conjugations (classes 1 and 3) to shift into class 2 over time.

 * OHG has both and, and Old Norse has , so a weak 2 verb was likely an original. Leasnam (talk) 04:15, 28 June 2023 (UTC)
 * There is also another reconstruction you may be interested in (if you have not yet seen it) at, which also lists 🇨🇬 as a descendant. Leasnam (talk) 04:19, 28 June 2023 (UTC)
