In our study of the spelling of English words we have found that there
are not many rules that apply. In fact, the only way to learn to spell
correctly is by sheer dint of memory.
In last week's lesson we found that a number of adjectives can be formed
from nouns or verbs by the addition of _able_ or _ible_, but we find it
difficult to determine whether to add _able_ or _ible_. The sound is
practically the same and we are confused as to whether we should use _a_
or _i_. There is no rule which applies in this case and there is nothing
to do but to master the spelling of these words by memory. These are
words which we use a great deal and which are very helpful members of
our working vocabulary.
Our list of words in this week's lesson contain some of the most common
words which we use ending in _ible_ or _able_. The words for Monday,
Tuesday, and Wednesday all end in _able_; the words for Thursday,
Friday, and Saturday will end in _ible_. Notice them carefully and get
fixed firmly in mind the correct spelling. Notice also that most of
these adjectives can be changed into adverbs by changing _ble_ to _bly_.
So when you have added these adjectives to your vocabulary, you have
also added the adverbs as well.
