Infinitive verbs end with -ti or -či.
Slovene mostly uses the present, past and future tenses.
In the present tense suffixes change according to plurality (singular, dual or plural) and grammatical person (1st, 2nd or 3rd person). They do not change for gender (masculine, feminine or neuter).
| singular | dual | plural | |||||||
|---|---|---|---|---|---|---|---|---|---|
| m | f | n | m | f | n | m | f | n | |
| 1st person | jaz sem | jaz sem | - | midva sva | midve sva | - | mi smo | me smo | - |
| 2nd person | ti si | ti si | - | vidva sta | vidve sta | - | vi ste | ve ste | - |
| 3rd person | on je | ona je | ono je | onadva sta | onidve sta | onidve sta | oni so | one so | ona so |
| singular | dual | plural | |
|---|---|---|---|
| 1st person | sem | sva | smo |
| 2nd person | si | sta | ste |
| 3rd person | je | sta | so |
| singular | dual | plural | |
|---|---|---|---|
| 1st | sedim | sediva | sedimo |
| 2nd | sediš | sedita | sedite |
| 3rd | sedi | sedita | sedijo |
| Note that the second e in sedeti changes to an i. | |||
| The -ti is removed leaving the root, sedi, to which suffixes are added. | |||
This is used to form both the past and future tenses.
The l-participle of a verb is formed by removing the -ti of the infinitive form and adding a suffix which starts with the letter "l".
The particular l-participle suffix that is used depends on the gender and the plurality but not on the grammatical person of the subject of the verb.
| singular | dual | plural | |||||||
| m | f | n | m | f | n | m | f | n | |
| 1st, 2nd, 3rd persons | ‑l | ‑la | ‑lo | ‑la | ‑li | ‑li | ‑li | ‑le | ‑la |
The past tense is formed by combining the relevant present tense form of the verb, biti (to be), with the appropriate form of the l-participle of a verb.
This holds true for forming the past tense of biti itself.
Using sedeti (to sit) as an example: we have seen that I sit (whether I refers to a male or female) is translated as sedim. I sat would be translated as sedel sem if the speaker was male and sedela sem if the speaker was female.
In summary, to form the past tense of a verb find the appropriate l-participle for the verb and combine it with the relevant form of the present tense of biti (to be).
The future tense of biti (to be) can be used on its own or as an auxillary verb together with the l-particple of another verb giving the future tense of the latter verb.
| singular | dual | plural | |
|---|---|---|---|
| 1st person | bom | bova | bomo |
| 2nd person | boš | bosta | boste |
| 3rd person | bo | bosta | bodo |
