בא על החתום

Etymology
From +  +  +.

Verb

 * 1)  To undersign.

Usage notes

 * This phrase is considered flowery, and used almost exclusively as the final clause of contracts and formal agreements to introduce the signatories.
 * The he of is vocalized with segol according to traditional norms, but is usually pronounced "ha-", like the normal pronunciation of the definite article. The extra formal pronunciation "... hekhatúm" is falling out of use.
