Questions & Answers about Tia ferio estus tre bona por mia onklino, ĉar ŝi amas la maron.
Estus is the conditional mood of esti (to be). It means would be.
So this sentence is talking about a possibility or a hypothetical situation:
- Tia ferio estus tre bona... = Such a vacation would be very good...
If you said estas, it would mean:
- Tia ferio estas tre bona... = Such a vacation is very good...
That sounds more like a general statement of fact, not a suggestion or imagined case.
Tia means such or that kind of.
It is used before a noun to describe the type or kind of thing:
- tia ferio = such a vacation, that kind of vacation
It belongs to the Esperanto correlative system:
- tio = that thing
- tia = that kind of, such
- tiel = in that way, thus
- tiam = then
So tia is the adjective-like form meaning of that sort.
