What does trunk mean?
Trunk is a versatile English noun whose core image is the thick main stem of a tree. From that central sense, it has developed into several familiar meanings: a large storage chest, the elongated nose of an elephant, and the enclosed luggage compartment at the back of a car, especially in American English. The word can also refer formally to the main part of a person's body or, in telecommunications, to a major long-distance telephone line. An archaic verb form once meant “to trust.” In ordinary modern usage, tree trunk is probably the most central compound, while phrases such as elephant's trunk and car trunk make the word's range especially memorable. Its usefulness lies in this combination of concrete imagery and practical application: one term links a tree's structural core, an elephant's remarkable nose, and the enclosed space where a car carries luggage.
A trunk is the main woody stem of a tree; by extension, the word also denotes a large storage chest, an elephant's nose, the human torso, a car's luggage compartment, or a major telephone line.
"The elephant reached over the fence with its trunk."
The tree, storage, elephant, and car senses are common in contemporary English. The torso sense is chiefly formal or literary, and the telephone sense is specialized.
The archaic verb trunk means “to trust.”
"The archaic phrase “I trunk thee” means “I trust you.”"
This form is obsolete in modern English; trust is the standard verb.
The usual plural refers to multiple tree stems, storage chests, or items of luggage.
"The movers carried three trunks into the bedroom."
An elephant's trunk is its nose, a car's trunk is its luggage compartment, and a tree's trunk is its main stem—one word with a remarkable range of identities.

Etymology of trunk
The word comes through Old French tronc, meaning a tree trunk or stump, from Latin truncus, a cut-off tree trunk or shortened form. The same Latin root also underlies English truncate and truncation, referring to shortening or cutting off. Its use in English developed from the literal tree stem to related ideas involving a main body, a projecting part, or a large principal container.
How trunk is actually used
In American English, the rear storage compartment of a car is usually called the trunk; in British English, boot is more common. The sense referring to the human torso is formal or literary, while the archaic verb meaning “to trust” is obsolete.
