Reconstruction:Proto-Celtic/writ-

From a root noun derived from Proto-Indo-European *wert- (“to turn”).

*writ-

1. against, opposite
2. towards
3. by, at, next to

• The reconstruction of this preposition is complicated.
  • Old Irish pretonic fris- and conjugation stem fris- are indicative of an original *writs. This cannot give the Brittonic forms, however.
  • Alternative Old Irish frith- and the Brittonic forms indicate a proto-form *writi.
• Gordon resolves the discrepancy by reconstructing a base root noun *writs, locative singular *writi, from which the two stems attested in Celtic can be derived.^[1]
• Schrijver takes *writi to be ancestral to all Celtic forms, but this dogma forces him to assume an irregular development -t > -ts- > -ss- for the Old Irish conjugated forms which is contradicted flagrantly by the 3rd-person singular forms of verbs (ending in *-ti).
• Matasović's reconstruction *writu-^[2] is incorrect, since it is phonologically impossible for Old Irish fri or its conjugated forms to come from this.
