Heavy Construction

The Allen and Greenough is still under construction; so some links may not work quite the way you would expect.


Adjectives expressing passive qualities, but occasionally active, are formed by means of the suffixes -

-ilis, -bilis, -ius, -tilis (-silis) frag-ilis, frail;
nó-bilis, well known, famous; nóscere (GNO), to know.
exim-ius, choice, rare (cf. é-greg-ius); eximere, to take out, select.
ag-ilis, active; agere, to drive.
hab-ilis, handy; habére, to hold.
al-tilis, fattened (see note); alere, to nourish.

NOTE: Of these, -ius is primary, but is also used as secondary (cf. § 241. b. N.). -ilis is both primary (as in agilis, fragilis) and secondary (as in similis, like, cf. oo , oo , English same); -bilis is in some way related to -bulum and -brum (§ 240. N.); in -tilis and -silis, -lis is added to to- (so-), stem of the perfect participle: as, fossilis, dug up (from fossus, dug); volátilis, winged (from volátus, flight).
