The spelling of the word "igive" can be explained using the International Phonetic Alphabet (IPA) transcription. The first syllable, "i", is pronounced as the sound /aɪ/, which represents the diphthong in words like "buy" or "eye". The second syllable, "give", is pronounced with the /g/ sound, followed by the short /ɪ/ vowel sound, and the voiced dental fricative /ð/ sound, represented as /gɪvð/, as in the word "give". The combination of these sounds gives us the word "igive".
