It is usually followed by a possessive suffix (forms given below) and a third-person singular form of the existential verb van (van/volt/lesz/lenne/legyen etc.), shown in the examples above, or támad(“to arise, crop up”), e.g. kosarazhatnékja támadt(“s/he felt the need to play basketball”), where the affected person is the possessive.
Another construction is with a verb like elfog, rájön, or rátör (here all mean “to overcome”), e.g. elfogja a sírhatnék(“s/he is overcome by the urge to cry, s/he feels the need to cry”), rájött a nevethetnék(“s/he was overcome by the need to laugh, s/he felt compelled to laugh”), where the affected person is either an object or a sublative argument required by the prefix rá- (both may be implicit if it's clear from the context).
