272 CLAUSES OF COMPARISON. [Par. 480-483.

480 In Elizabethan English " as" is used, where we
use "that," before an Indicative: —
(2) " Thou hast given the house of York such head
as thou shalt reign but by their sufferance."
(3) " Such signs of rage they bear as it seemed they
would debate with angry swords."
(4) " If a man have that penetration of judgment as
he can discern what things are to be laid open."
This use of "as" is now a vulgarism.
481 " So that" (- "in that way, in which way")
naturally expresses purpose with the Mood of Purpose: -
(1) " Work so (in that way) that (in which way) you
may earn your bread."
482 Lest" is a contraction for "by which the least
or less " (compare the Latin " quominus "). " Be
careful lest you may make a mistake, i.e. by which
(care) you may the less (probably) make a mistake."
Clauses of Comparison.
483 "As " is a contraction of "all-so," "alse," and
means sometimes " in which way," sometimes (like
" so ") "in that way." Consequently " as" is, by
derivation, an emphatic form of " so." Hence the
words are sometimes very similarly used: —
(1) "IIe is not so clever as you."
(2) " He is as clever as you."
