Etymology

'Cæg's spur of land,' the first of the very numerous examples of hoh in Bedfordshire names and a clear example of its general topographical sense, for it lies on a spur of land running down sharply to the junction of two (unnamed) streams. The pers. name Cǣg is not found in independent use in OE, but it is found in the same compound in Cassio(bury) (Herts), Cægesho in BCS 267. For the weak form of this name, v. Cainhoe infra 147 and IPN 180. For DB -t , cf. DBAsceshot = Ashow (Wa).
