The spelling of the word "gatica" can be explained through its IPA phonetic transcription. The word is pronounced as ɡəˈti.kə, with stress on the second syllable. The initial "g" is pronounced as a voiced velar stop, followed by a schwa sound, then a stressed "ti" pronounced as a voiceless alveolar stop and an "i" sound. The final syllable is pronounced as a schwa sound followed by the voiceless alveolar consonant "k", and an "ə" sound. This pronunciation can help avoid any confusion while spelling the word.
