"Lia kuzo alvenis je la deka."

Translation: His cousin arrived at ten.

[Snugglesworth]

What if I wanted to say his cousin arrived on the tenth? Like tenth of May. Wouldnt i use je for that, too? En doesnt feel right.

Tio okazis la dekan. = Tio okazis en la deka tago de la monato.

Tio okazis je la deka. = Tio okazis je la deka horo de la tago.

[Flink91]

I don't understand this sentence. What is la deka? The tenth of what?

[fdsimms]

The tenth hour, I would guess, so like ten o'clock

[Flink91]

Makes sense! Thank you! :)

[carrots084]

I was understanding it as "He arrived tenth" like tenth place

Why not "ĉe dek"?

[AlexeiNewt]

"ĉe" is only used for someone/something's location in space, not time. Also, "dek" is only used for the number, rather than the time.

How do i know when to use en and when to use je?

[StephieRice]

Je is only used when no other preposition fits appropriately.

[HunterJuar]

What's the difference between apud, cxe and je

[StephieRice]

Apud = beside
Cxe = at
Je = that preposition that is used when no other preposition exists that can accurately conveybthe meaning

[blovemaple]

Je is used to replace another preposition, but what preposition does it replace here?

[AlexeiNewt]

Je is used when we know there should be a preposition, but aren't quite sure what preposition to use, or when there isn't a specific preposition for it.
