Formation of the Future Perfect Tense

The future perfect tense in Lithuanian grammar is formed by combining the future tense of the auxiliary verb ‘būti’ (to be) with the past active participle of the main verb. The auxiliary verb ‘būti’ changes according to the subject, while the past active participle remains the same for all subjects.

Here is the future tense conjugation of the auxiliary verb ‘būti’:

• Aš būsiu – I will be
• Tu būsi – You will be
• Jis/ji būs – He/she will be
• Mes būsime – We will be
• Jūs būsite – You (plural) will be
• Jie/jos būs – They will be

To create the past active participle of the main verb, simply replace the -ti ending with -ęs for masculine nouns and -usi for feminine nouns.

For example, the verb ‘parašyti’ (to write) becomes:

• parašęs (masculine)
• parašiusi (feminine)
