Wonder what’s the relation between ‘Chanda Jamaa Karnaa’ and saying ‘Chande Aftab Chande Mahtaab’ while complimenting someone’s beauty? It’s the word ‘Chand’. This Persian word means ‘inasmuch as (Kisi Qadar)’, ‘a little (ThoDaa Saa)’, ‘somewhat (Kuchh)’.
Guzari thi Khushi ki chand ghaDiyaan
Unhii.n ki yaad merii zindagi hai
In Urdu, this word inflected to become ‘Chandah (donation)’, for when a donation is collected for a purpose, doners contribute many small, little values. 
Also, when it comes to praising someone’s good looks, the expression ‘Chande Aftab Chande Mahtaab’ means he/she is somewhat like Sun, and somewhat like Moon.
The word ‘Chand’ also gives way to ‘Chandaa.n’ which is quite often used like this:
“Aap ko is Mu’aamile mein fikr karne ki chandaa.n zaruurat nahin, main huun naa.”
Here Chandaa.n means hardly, little or no, but is also used in the sense of absolutely or Bilkul. 

You must've heard of the phrase 'Naubat Bajaanaa'.
But did you know, at the door of the elites and kings, the trumpet that played at a fixed time or at a special occasion was called 'Naubat'. It's ensemble included Naqqara (drum), Tabl (Tabla), and Nafiirii, which was a Bansuri like instrument. When all three were played along, it was called Naubat Bajaana. The place where it was played was known as Naubat-Khaana.

Moreover, the word Naubat is also used in the sense of bad condition, ill-state. There's also a proverb around it, 'Naubat Aanaa'. Eg., "Wo khaandaani raees the lekin ab ye naubat aa gayi, dusron ke aage haath phailaana padta hai".

This proverb has been versified like this:
Main Aaiina banuunga to paththar uthaaega
Ek din khulii saDak pe ye Naubat bhi aaegi

The word ‘Ustaad’ entered the Urdu language from Persian. Its journey began with the religious Zoroastrian book Awista, which was in the ancient Iranian language and had very few people who understood it. The person who understood Awista was known as ‘Awista-wed’. The word ‘wed’ is still used for ‘Hakim (wise)’, or ‘Daanaa (learned)’. Gradually, the word first became ‘Awista-wid’, and then morphed into ‘Ustaad’. Originally, the word was used only for those who understood religious texts, but later became an appellation for everyone who taught and tutored. Nowadays, a master of an art or a skill is referred to as Ustaad, too. The word has become an inseparable part of the names of the virtuosos of Indian classical music. Today, in everyday speech, the word has taken a new meaning; being artful has come to be known as Ustaadi dikhaana. Endearingly, friends too address each other as Ustaad these days. In Indian films, characters of all sorts are depicted as Ustads, and films named ‘Ustadon ke Ustad’, ‘Do Ustad’, and ‘Ustadi, Ustad Ki’ are also found.
