Syn, -- Because, For, Since, As, Inasmuch As. These particles are
used, in certain connections, to assign the reason of a thing, or
that "on account of" which it is or takes place. Because (by cause)
is the strongest and most emphatic; as, I hid myself because I was
afraid. For is not quite so strong; as, in Shakespeare, "I hate him,
for he is a Christian." Since is less formal and more incidental than
because; as, I will do it since you request me. It more commonly
begins a sentence; as, Since your decision is made, I will say no
more. As is still more incidental than since, and points to some
existing fact by way of assigning a reason. Thus we say, as I knew
him to be out of town, I did not call. Inasmuch as seems to carry
with it a kind of qualification which does not belong to the rest.
Thus, if we say, I am ready to accept your proposal, inasmuch as I
believe it is the best you can offer, we mean, it is only with this
understanding that we can accept it.
