Page "Grammatical tense" Paragraph 5

The term tense is therefore at times used in language descriptions to represent any combination of tense proper, aspect, and mood, as many languages include more than one such reference in portmanteau TAM ( tense – aspect – mood ) affixes or verb forms.

Conversely, languages that grammaticalise aspect can have tense as a secondary use of an aspect.

In many languages, such as the Latin, Celtic and Slavic languages, a verb may be inflected for both tense and aspect together, as in the passé composé / passé simple ( historique ) and imparfait of French.

Verbs can also be marked for both mood and tense together, such as the present subjunctive ( So be it ) and the past subjuncitve ( Were it so ), or all three, such as the past perfect subjunctive ( Had it been so ).
