Periodic tense

Periodic tense is a subtype of the grammatical category of tense, which encodes that the event expressed by the verb occurs within a particular period of the day (such as 'at night', 'in the morning' etc.) or of the year ('in winter', 'in summer' etc.). Its does not encode a relation to a particular point of reference, unlike deictic tense, the grammatical expression of time reference (usually past, present or future) relative either to the moment of speaking (absolute tense) or to another point of reference (relative tense).

Periodic tense is geographically restricted to Northern America, the Western Amazon region, the area of the Sepik River in Papua New Guinea, Arnhem Land in Australia and is almost entirely absent from languages of Africa and Eurasia, with the exception of Chukotkan languages.^: 12–14

Periodic tense in Nez Perce

Periodic tense can be illustrated with data from Nez Perce, which has one of the richest paradigms, comprising matutinal, diurnal, vesperal, nocturnal and hivernal, as illustrated in the following examples

Reconstructibility

Periodic tense systems are at least partially reconstructible in some language families. In proto-Sahaptian for instance, nocturnal *têw- and matutinal *mêy-, from which Nez Perce nocturnal te·w- and matutinal méy- above originate, have been reconstructed by Aoki (1962).

In Tacanan languages, four periodic tense markers are reconstructible,^: 16 whose reflexes in Cavineña or the following: diurnal -chinepe, nocturnal -sisa, auroral -wekaka and vesperal -apuna (Guillaume 2008:126).

Attested subtypes

17 subtypes of periodic tense markers have been identified in Jacques (2023:7, Table 2), with a latinate terminology for each specific time period.
