ap-pet

アッベツ ‘winding river’ proposed
  • ap ‘bend, curve’
  • pet ‘river’

Proponent: zenibako_trek(小樽銭函地名歴史研究会) (zenibako_trek (Otaru Zenibako Place-Name and History Society))

The same reading the author gives to the Atsubetsu of Hidaka at Atsuga, where he derives the sense of ap from nut-ap 'the bend of a river'.

Confidence: low

pet is a dictionary word in the sense used; the sense of ap the reading needs is the author's, the dictionary sense being 'fishhook'.

A-pet

‘The river tine’ proposed
  • A ‘prong of a fork, tine’
  • pet ‘river’

Proponent: John Batchelor

A is a prong of a fork or tine: pet is river.

Confidence: low

Batchelor's reading and gloss as printed in 1905; the segmentation is his, and several of its elements answer to no dictionary headword.
