Final answer:
Diacritical marks are used in dictionary word entries to indicate pronunciation. [k] is spelled 'ck' after a short vowel and 'ke' after a long vowel at the end of words. A silent final 'e' can make a 'g' soft, as in 'geography'.
Step-by-step explanation:
The special marks in the pronunciation of the dictionary word entry are called diacritical marks. In words in which [k] follows a consonant and is in turn followed by an that comes at the end of the word, the [k] is spelled ck.
In words that have a [k] right in front of an that comes at the end of the word and a vowel with strong stress right in front of the [k], the [k] is spelled c if the vowel is short, and it is spelled ke if the vowel is long. For instance, the word speck has a short vowel followed by [k], thus it is spelled with c; and the word bike has a long vowel followed by [k], thus it is spelled with ke.
A silent final will mark a right in front of it as being soft—that is, as spelling the sound [j]. An example of this rule would be the word 'geography', where the g is soft.
To summarize how to spell the sound [k] at the end of words:
- After a short vowel and at the end of the word, such as in tick or deck, [k] is typically spelled ck.
- After a long vowel and at the end of the word, such as in flake or stroke, [k] is spelled ke.
