nominative or accusative singular + conjunction (sandhi form)
Analysis. taṃ (accusative singular of ta, 'that') + ca (conjunction 'and'); the final -ṃ drops before ca, leaving tañ; the -ñ- is the palatal nasal arising from the dental nasal + the velar stop of ca in sandhi.
Etymology. ta is the demonstrative pronoun from Indo-European *to- (cognate with Latin is, English the, Greek to); ca 'and' is cognate with Latin que, Sanskrit ca, and the conjunction 'and' across Indo-European languages.
