====''Haber'': personal obligation====
A separate construction is ''haber de'' + infinitive. It is not impersonal. It tends to express a certain nuance of obligation and a certain nuance of future tense, much like the expression "to be to". It is also often used similarly to ''tener que'' and ''deber'' ("must", "ought to"). Note that the third personal singular of the present tense is ''ha''.

*''Mañana he de dar una charla ante la Universidad'' = "Tomorrow I am to give a speech before the University".
*''Ha de comer más verduras'' = "She/he ought to eat more vegetables".
