Syn: Syn. Loneliness; soitariness; loneness; retiredness;
recluseness. -- {Solitude}, {Retirement}, {Seclusion},
{Loneliness}.

Usage: Retirement is a withdrawal from general society,
implying that a person has been engaged in its scenes.
Solitude describes the fact that a person is alone;
seclusion, that he is shut out from others, usually by
his own choice; loneliness, that he feels the pain and
oppression of being alone. Hence, retirement is
opposed to a gay, active, or public life; solitude, to
society; seclusion, to freedom of access on the part
of others; and loneliness, enjoyment of that society
which the heart demands.

O blest retirement, friend to life's decline.
--Goldsmith.

Such only can enjoy the country who are capable
of thinking when they are there; then they are
prepared for solitude; and in that [the country]
solitude is prepared for them. --Dryden.

It is a place of seclusion from the external
world. --Bp. Horsley.

These evils . . . seem likely to reduce it [a
city] ere long to the loneliness and the
insignificance of a village. --Eustace.
