The spelling of the word "learnt ins outs" can be a bit tricky for English learners. In IPA phonetic transcription, it is represented as /lɜːnt ɪnz aʊts/. The "-nt" ending is common in British English, while American English usually uses "-ed." "Ins" and "outs" are just spelled as they sound, but the "s" at the end of "outs" indicates it is plural. "Learned" is also an acceptable spelling, but "learnt" is more commonly used in British English.
