Questions & Answers about Моя любимая скатерть уже лежит на столе.
Why do we use лежит here instead of класть or положить?
Лежит (from лежать) is an intransitive verb of state meaning "to be lying." We use it here because the tablecloth is already in its resting position. If someone were actively placing it on the table, we would use the transitive verb of positioning класть (to put/lay) or its perfective pair положить.
Why does the sentence use на столе instead of на стол?
Because лежать describes a static location (where something is), we use the preposition на with the Prepositional case (на столе). If we used an active positioning verb like класть, we would need the Accusative case to show the direction or destination of the action (на стол - onto the table).
The word скатерть ends in a soft sign (-ь). How can I tell its gender?
Russian nouns ending in a soft sign can be either masculine or feminine. In this sentence, the feminine modifiers моя and любимая are the big clue! Скатерть is a feminine noun, meaning it follows the 3rd declension pattern (just like дверь or ночь).
Could we use стоит (is standing) for a tablecloth?
