The sound /k/ is used in the common suffix "-ic". This suffix appears in adjectives and usually means "of" or "relating to".
The sound /k/ is also used in the suffix "-ical," which also appears in adjectives and usually has the same meaning as "-ic." However, "-ic" and "-ical" may mark words with different meaning. (For example, "economic" and "economical" have different meanings, and "comic" and "comical" also have different meanings.)
These are both voiceless consonants pronounced in the back of the mouth. However, /k/ is a velar stop and /h/ is a glottal fricative. The sound /k/ is pronounced with the back of your tongue, while /h/ is pronounced with the glottis, which is behind your tongue.
You can hear the difference between /k/ and /h/ in these words.
1. A. call, B. hall 2. A. kit, B. hit 3. A. come, B. hum 4. A. cook, B. hook 5. A. keep, B. heap 6. A. racecourse, B. racehorse
Now practice /k/ in sentences. Say the words first, then the sentences.
1. thank - kind - encouragement Thank you for your kind encouragement. 2. can - park - covered We can park in a covered garage. 3. exchange ("x" = /ks/) - cards - Christmas They exchange cards and gifts for Christmas. 4. clean- kitchen - cook Please clean the kitchen after you cook. 5. stack - boxes ("x" = /ks/) - corner Stack the boxes in the corner. 6. calculus - textbook ("x" = /ks/) - class I need a calculus textbook for my class.
