Necesitasteis

necesitasteis is the second-person plural preterite form of the verb necesitar in Spanish. It translates to “you all needed” and is used with the informal plural subject vosotros or vosotras. This form is characteristic of Castilian Spanish, where the vosotros form is common. In much of Latin America, the vosotros forms are not used, and the past tense for ustedes is typically "necesitaron."

As a regular -ar verb in the preterite, necesitasteis is formed by adding the ending -asteis to the stem necesit- (necesit- + -asteis). This makes it part of the standard pattern for vosotros in the preterite: -asteis for -ar verbs.

Usage notes: necesitasteis denotes a completed past action or state in which you all needed something. It is usually used in informal plural contexts or in written narration that uses vosotros. In regions that do not use vosotros, this form is uncommon and may be replaced by the ustedes form, with the corresponding preterite ending -aron (necesitaron).

Examples:

- ¿Qué necesitasteis para la excursión? (What did you all need for the trip?)

- Necesitasteis más tiempo para terminar el informe. (You all needed more time to finish the report.)
