the word for "stairs" or "stairway" in most of the Empire is letlh. One type of letlh is a choghvat, the stairway leading to and from the doorway of a ship. In a couple of dialects in the Mekro'vak (meqro'vaq) region, however, letlh refers only to the stairway connected to a ship, while ngep'oS is any other kind of stairway but not one used to enter or exit a ship. (KGT p. 29)

Sometimes qach choghvat, sometimes choghvat pa'. This word (which is really the word for "gangplank") is used for this part of a structure even if there are no stairs or ramps involved.
(qep'a' 2020)

choghvat "[...] does have to be attached to a house or building or something or other. It doesn't necesarily have to have a roof. It doesn't necesarily have to have a little fence around it. It's the outside entryway to the building. (Q&A 52:18) A ramp or steps leading to a porch would not be called a choghvat, just steps or whatever. They would if they would be leading all the way up to a boat." (Q&A 53:00)
