The word "inscr" has an unusual spelling that may be confusing to many. However, the spelling is actually based on the phonetic transcription of the word "inscribe" using the International Phonetic Alphabet (IPA). The IPA symbol for the "k" sound is "k", while the "b" sound is represented by the "b" symbol. Therefore, "inscribe" is transcribed as /ɪnˈskraɪb/. To create a shortened version of the word, the "ibe" ending is replaced with "r", resulting in the spelling "inscr".
