@Loh Jane,
Many houses can a person have, but only one home
Many houses but only one home can a person have
A person can have many houses but only one home (one home only)
One can possess many houses (many a house) but (tho) just one home
Though anybody might possess any number of houses, he can have just one home
Many a house though he might own, only one home can he possess
Good gosh Mark what is it with you this morning anyhow
