Besides the above may be noted

WONT (_sub._): lost in _won't_ = will not.

FAIR: Though we still speak of 'a fair complexion' the
word has lost much of its old use: and the verb TO FARE has
suffered; we still say 'Farewell', but scarcely 'he fares
ill'; also TO FARE FORTH is obsolete.

BOLT = to sift, has gone out, also BOLT in the sense of a
missile weapon; but the weapon may have gone first; we still
preserve it in 'a bolt from the blue', a thunder-bolt, and 'a
fool's bolt is soon shot', and we shoot the bolt of a door.

BARM: this being the name of an object which would be familiar
only to brewers and bakers, probably suffered from the
discontinuance of family brewing and baking. It would no
longer be familiar, and may possibly have felt the blurring
effect of the ill-defined BALM, which word also seems rarely
used. In the South of England few persons now know what barm
is.

ARCH: _adj._, probably obsolescent.

There are also examples of words with the affix a-, or initials
simulating that affix, thus:

ABY: lost in _abide_, with which it was confused.

ABODE = bode (? whether ever in common use).
