PREFIXES.
A favourite way of building words is by the use of prefixes. Generally speaking, these are of English, French, Greek or Latin origin—it being understood in this connection that French is but a modified form of Latin.
English Prefixes.
Inseparable prefixes have no meaning in themselves and cannot stand alone. The most important are:—
A-, on: away, alive; at: ahead: of: akin.
And-, against (Greek anti-): answer (sweri-an, to declare).
