Answer:
I am a daily ritual involving using a metal tool on the body
The letter S is added to pluralise most words in the English language. eg. Letter to Letters Word to Words and Language to Languages. But I am a word that is pluralised with the addition of the letter C.
I begin with the letter “i”, if you add “a” in front of me, I become a new word with a different meaning, but still sounds exactly the same. What word am I?
I have no voice but I can teach you all there is to know. I have spines and hinges but I am not a door. Once I’ve told you all I cannot tell you more.
You can never eat me for breakfast or lunch. What am I?
I repeat only the last word you say. The more I repeat, the softer I got. I cannot be seen but can be heard. What am I?
