109. Rules of combination

Principles of Euphonic Combination.

109. The rules of combination (saṁdhi 'putting together) are in some respects different, according as they apply—

a. to the internal make-up of a word, by the addition of derivative and inflectional endings to roots and stems;

b. to the more external putting together of stems to make compound stems, and the yet looser and more accidental collocation of words in the sentence;

c. Hence they are usually divided into rules of internal combination, and rules of external combination.
