A good way to remember is: "Escalera" sounds like "escalate " so when you climb up the ladder/stairs, you are escalating. :} hope this helps somebody! :D

"He has a ladder." is wrong because Duolingo has "Él tiene la escalera.", and 'la' means 'the' not 'a'. Hope this helps! :D
We wouldn't say 'he has the staircase in English' it sounds wrong. We would say'he takes the stairs' or 'he has a staircase' [presumably in his house].
Actually, the other day my brother did have the staircase. We were putting damp proofing in the basement and we went to dismantle the staircase to get full access to the wall it was touching. Surprisingly to us, it was only fixed in with two bolts and the whole staircase moved away from the wall as a unit.
'He has the stair' should also be accepted, since 'escalera' also means 'stair'.
I dont know if any of you are having the same problem, but it keeps telling me I'm wrong when I'm right. I know I'm correct because it clearly says I'm right as I'm writing what it says is the correct answer.
This is "he has the ladder" but I think I've answered "he takes the stairs" 20 times by now...
