CONDITIONAL MOOD.
The Conditional or US mood has no tenses (see par. [192]). We can show its meaning best by using the conjunction se, which frequently introduces it. It has no time value in itself, and may relate to the past, present, or future.
| Sing. | (Se) | Mi | estus | = (If) I should be, were, had been. |
| (Se) | Vi | estus | = (If) you would, were, had been. | |
| (Se) | Li, etc. | estus | = (If) he would, were, had been. | |
| Plural. | (Se) | Ni | estus | = (If) we would, were, had been. |
| (Se) | Vi | estus | = (If) you would, were, had been. | |
| (Se) | Ili | estus | = (If) they would, were, had been. |
