Let \Let\, v. t. [imp. & p. p. {Let} ({Letted} (l[e^]t"t[e^]d),
[Obs].); p. pr. & vb. n. {Letting}.] [OE. leten, l[ae]ten
(past tense lat, let, p. p. laten, leten, lete), AS.
l[=ae]tan (past tense l[=e]t, p. p. l[=ae]ten); akin to
OFries. l[=e]ta, OS. l[=a]tan, D. laten, G. lassen, OHG.
l[=a]zzan, Icel. l[=a]ta, Sw. l[*a]ta, Dan. lade, Goth.
l[=e]tan, and L. lassus weary. The original meaning seems to
have been, to let loose, let go, let drop. Cf. {Alas},
{Late}, {Lassitude}, {Let} to hinder.]
1. To leave; to relinquish; to abandon. [Obs. or Archaic,
except when followed by alone or be.]

He . . . prayed him his voyage for to let.
--Chaucer.

Yet neither spins nor cards, ne cares nor frets,
But to her mother Nature all her care she lets.
--Spenser.

Let me alone in choosing of my wife. --Chaucer.

2. To consider; to think; to esteem. [Obs.] --Chaucer.

3. To cause; to make; -- used with the infinitive in the
active form but in the passive sense; as, let make, i. e.,
cause to be made; let bring, i. e., cause to be brought.
[Obs.]

This irous, cursed wretch
Let this knight's son anon before him fetch.
--Chaucer.

He . . . thus let do slay hem all three. --Chaucer.

Anon he let two coffers make. --Gower.

4. To permit; to allow; to suffer; -- either affirmatively,
by positive act, or negatively, by neglecting to restrain
or prevent.

Note: In this sense, when followed by an infinitive, the
latter is commonly without the sign to; as to let us
walk, i. e., to permit or suffer us to walk. Sometimes
there is entire omission of the verb; as, to let [to be
or to go] loose.

Pharaoh said, I will let you go. --Ex. viii.
28.

If your name be Horatio, as I am let to know it
is. --Shak.

5. To allow to be used or occupied for a compensation; to
lease; to rent; to hire out; -- often with out; as, to let
a farm; to let a house; to let out horses.

6. To give, grant, or assign, as a work, privilege, or
contract; -- often with out; as, to let the building of a
bridge; to let out the lathing and the plastering.

Note: The active form of the infinitive of let, as of many
other English verbs, is often used in a passive sense;
as, a house to let (i. e., for letting, or to be let).
This form of expression conforms to the use of the
Anglo-Saxon gerund with to (dative infinitive) which
was commonly so employed. See {Gerund}, 2. `` Your
elegant house in Harley Street is to let.''
--Thackeray. In the imperative mood, before the first
person plural, let has a hortative force. `` Rise up,
let us go.'' --Mark xiv. 42. `` Let us seek out some
desolate shade.'' --Shak.

interfering with.

charge of, as a gun.
(b) To release, as from an engagement or obligation.
[Colloq.]

(b) To extend or loosen, as the folds of a garment; to
enlarge; to suffer to run out, as a cord.
(c) To lease; to give out for performance by contract, as
a job.
(d) To divulge.

{To let slide}, to let go; to cease to care for. [Colloq.] ``
Let the world slide.'' --Shak.
