A Productive Dual Form

Level 3

Learn complete forms: sena/sentejn, ġimgħa/ġimagħtejn and rkoppa/rkopptejn.

How It Works

Some nouns have a dual, especially body parts, time periods and traditional measures. The ending often contains -ejn, but learn the whole form: sena/sentejn and ġimgħa/ġimagħtejn. Stem changes prevent simple addition to every singular. The wider dual category also includes -ajn, as in saqajn.

An ordinary exact-two dual needs no extra numeral: sentejn, ‘two years’, contrasts with tliet snin, ‘three years’. Nouns without a dual use numeral phrases, such as żewġ kotba, ‘two books’. Dual nouns take plural verb and adjective agreement; adjectives have no separate dual ending.

Body-part forms can extend beyond exactly two. Rkopptejn also functions as a plural, and other body-part duals occur in broader or idiomatic uses. Their shape alone therefore does not settle the number intended in every context.

Examples (3)

  1. Stennejna sentejn.

    We waited two years.

    The dual supplies the duration without another numeral.

  2. Ħdimt hemm ġimagħtejn.

    I worked there for two weeks.

    The lexical dual identifies two weeks.

  3. rkoppa — rkopptejn

    a knee — two knees

    Morphological contrast fragment; rkopptejn also functions as a plural.
