Another type of existential usage is in clauses of the "there is..." or "there are..." type. Languages differ in the way they express such meanings; some of them use the copular verb, possibly with an expletive pronoun like the English "there", while other languages use different verbs and constructions, like the French "il y a" (which uses parts of the verb "avoir" "to have," not the copula "être") or the Swedish "finns" (the passive voice of the verb for "to find"). For details, see existential clause.
