| 词根词缀 | 词源： late 13c., of unknown origin, possibly related to O.Fr. escalpe "thin fragment of wood," which seems to be a Gaulish loan word (cf. Bret. scolp, Welsh ysgolp "splinter, chip"). But OED rejects this on formal grounds. Meaning "rectangular block of pre-cast concrete used in building" is from 1927. |
