n

Etymology
The word 'pram' is a shortening of the earlier term 'perambulator', which itself derives from the Latin verb 'perambulare', meaning 'to walk through, to traverse'. The original perambulator was a wheeled device for measuring distances. In the 19th century, the term was humorously applied to the new baby carriages, as they were also wheeled vehicles 'walked through' the streets by a nurse or parent. The clipped form 'pram' emerged as a convenient colloquialism and became the standard term in British English, completely shedding its original association with measurement.
Analysis
This word is a simplex loanword. It does not contain separable morphemes within its modern English spelling.
