In favor of the Indo-Hittite hypothesis are the very Indo-European agricultural terminology conserved in Anatolia, otherwise considered the cradle of agriculture, and the laryngeal theory that hypothesizes the existence of one or more additional stop or spirant consonants in the Indo-European parent language that has only been attested in Hittite and of which only traces are left outside Anatolian.

Since the ending was * "-ta " in late Proto-Indo-European, the suffix should have undergone Grimm's law and become * "-?" in Germanic whenever the verb stem did not end in an obstruent, but remained as * "-t " when the stem ended in an obstruent, because of the spirant law.

"p ", " t ", and " k " did not undergo Grimm's law after a fricative ( such as s ) or after other plosives ( which were shifted to fricatives by the Germanic spirant law ); for example, where Latin ( with the original t ) has stella " star " and octo " eight ", Middle Dutch has ster and acht ( with unshifted t ).

According to Whitman's research there are two spirant + nasal consonant clusters that have been found, which are " hm ", as in " s�hm?" ('seven') and " hn ", as in " l�hniwe " ('calumet'), however Whitman does account that " h?" is a combination which appears as a future tense suffix . and thus appears to be another possible spirant + nasal consonant combination.
