^^ The song has no relation from the topic , put its from one of my favorite boy band and my poem shares the same tittle with it.

-----------------------------------------------------------

The 7-letter word that deserves the most respect;

The 7-letter word whose master at every aspect.

The 7-letter word who is full of knowledge and earnings;

The 7-letter word who is here for more than just earnings.

The 7-letter word through high and low;

The 7-letter word for every shy and show.

The 7-letter word who gives scolding;

The 7-letter word who is expert at molding.

The 7-letter word, a symbol of love, security and care;

The 7-letter word who's always ready to share.

The 7-letter word who is the best preacher;

This 7-letter word is called Teacher.

Happy Teacher's day people. This one is for @MuskanLeharwani for suggesting me to update it.
