150. Only one consonant

In general, only one consonant, of whatever kind, is allowed to stand at the end of a word; if two or more would etymologically occur there, the last is dropped, and again the last, and so on, till only one remains.

a. Thus, tudants becomes tudant, and this tudan; udañc-s becomes udan̄k (142), and this udan̄; and achāntst (s-aor., 3d sing., of √chand [890b]) is in like manner reduced to achān.

b. But a non-nasal mute, if radical and not suffixal, is retained after r: thus, ū́rk from ūrj, várk from √vṛj, avart from √vṛt, ámārṭ from √mṛj, suhā́rt from suhārd. The case is not a common one.

c. For relics of former double finals, preserved by the later language under the disguise of apparent euphonic combinations, see below, 207 ff.
