📝 Conjugation Notes
いたします is the humble form of する (suru). It conjugates like a regular ます-form verb: – Present/Future Affirmative: いたします – Present/Future Negative: いたしません – Past Affirmative: いたしました – Past Negative: いたしませんでした – Volitional: いたしましょう
🔊 Pronunciation Tips
Pronounced “i-ta-shi-ma-su”. Make sure to pronounce each syllable clearly. The “i” is short, and the “u” at the end of -masu is often devoiced, sounding more like “mas”.
🧠 Memory Tips
Remember that いたします is the humble partner to する. Think of it as “humbly I do”. It replaces します when you need to lower yourself to raise the listener.
