SUMMER REVISION
ENGLISH LANGUAGE (5.).
One of the commonest errors
in written English is the placing.
of words in the wrong place and this alter the meaning of the whole. Look at these sentences:
1. I only walked as far
Ferry.
2. I walked only as far as
Ferry.
Only I walked as far as
Star
In the first case, it meant that he didn't run or ride or go by any other means to reach Star Ferry,
In the second case, it meant that he walked as far as Star Ferry and no further.
In the third case, it meant that no one else walked with him as far as Star Ferry..
these
From the
examples, we can
see how a wrongly placed word, could change the meaning of the entire sentence. Care should therefore be taken especially wher
using the following words:
almost, even, and,
hardly, just, scarcely.
quite, nearly,
