There are a few more rules governing the spelling of derivative words.
Words ending in silent _e_ keep the _e_ before the suffix beginning with
a consonant. Notice the following words:
excite excitement
like likeness
force forceful
shame shameless
lone lonesome
live lively
Words ending in silent _e_ drop the _e_ before the suffix beginning with
a vowel, as:
excite excitable
live living
grieve grievous
force forcible
Some words ending in silent _e_ retain the _e_ before the suffix
beginning with a vowel, to prevent a change in the pronunciation or to
preserve the identity of the word. Notice the following words:
peace peaceable
courage courageous
singe singeing
change changeable
shoe shoeing
notice noticeable
These are words ending in the soft sound of _c_ and _g_, where the _e_
is retained to preserve the correct pronunciation of the _c_ and _g_,
and with some few words like _toe_, _dye_, etc., where the dropping of
the _e_ would lose the identity of the word.
The _e_ is dropped in a few words before the suffix beginning with a
consonant, as in _wholly_, _nursling_, _judgment_, _wisdom_, _lodgment_.
Add the suffixes _ment_ and _ing_ to the words in Monday's lesson; the
suffix _able_ to the words for Tuesday and Wednesday; the suffixes
_some_ and _ous_ to the words for Thursday; the suffixes _ly_ or _ness_
to the words for Friday and Saturday.
