The spelling of the word "caprin" can be explained using the International Phonetic Alphabet (IPA). The first sound is /k/ which is pronounced as a hard "k" sound. The second letter is represented by the schwa sound /ə/ which is a weak vowel sound. The third and fourth sounds are /p/ and /r/ respectively, which are pronounced as a hard "p" sound and a rolling "r" sound. The final sound is /ɪn/, which is pronounced as the "in" sound. Therefore, the IPA transcription for "caprin" would be /ˈkæprɪn/.
