Final answer:
The correct spelling of 'accommodate' combined with 'ion' is 'accommodation', and various other word combinations such as 'digestion' and 'spiritual' demonstrate the base words combined with suffixes or other modifiers without altering the base spelling.
Step-by-step explanation:
The correct spelling for the combination of accommodate and ion is accommodation. When combining these words, we retain the base spelling of 'accommodate' and simply add on the 'ion' without any changes to form the word 'accommodation'. This follows the standard rule of maintaining the base word's spelling when suffixes are added, unless there is a specific grammatical rule that dictates otherwise, which in this case, there is not.
Prefixes, Bases, and Suffixes
- digestion from dis + gest + ion
- spiritual from spirit + ual
- questioner from question + er
- actually from act + ual + ly
- adventurous from ad + vent + ure + ous
- scriptural from script + ure + al
- literature from liter + ate + ure
It is noteworthy that the word 'digestion' contains the [ch] sound spelled as due to palatalization that occurs when combining 'dis' and 'gest' with the suffix 'ion'.
