The word(s) "under" appears 194 time(s) in 189 verse(s) in Quran in Mohsin Khan translation.

(141) It is He, Who has created you (Adam) from dust, then from a Nutfah [mixed semen drops of male and female sexual discharge (i.e. Adam's offspring)] then from a clot (a piece of coagulated blood), then brings you forth as an infant, then (makes you grow) to reach the age of full strength, and afterwards to be old (men and women)- though some among you die before,- and that you reach an appointed term in order that you may understand.

(142) And they say: "Our hearts are under coverings (screened) from that to which you invite us; and in our ears is deafness, and between us and you is a screen: so work you (on your way); verily, we are working (on our way)."

(143) But if they turn away, then say (O Muhammad صلى الله عليه وسلم): "I have warned you of a Sa'iqah (a destructive awful cry, torment, hit, a thunderbolt) like the Sa'iqah which overtook 'Ad and Thamud (people)."

(144) And as for Thamud, We showed and made clear to them the Path of Truth (Islamic Monotheism) through Our Messenger, (i.e. showed them the way of success), but they preferred blindness to guidance; so the Sa'iqah (a destructive awful cry, torment, hit, a thunderbolt) of disgracing torment seized them because of what they used to earn.

(145) And those who disbelieve will say: "Our Lord! Show us those among jinn and men who led us astray: that we may crush them under our feet so that they become the lowest."

(146) And if We had sent this as a Qur'an in a foreign language (other than Arabic), they would have said: "Why are not its verses explained in detail (in our language)? What! (A Book) not in Arabic and (the Messenger) an Arab?" Say: "It is for those who believe, a guide and a healing. And as for those who disbelieve, there is heaviness (deafness) in their ears, and it (the Qur'an) is blindness for them. They are those who are called from a place far away (so they neither listen nor understand)."

(147) Nearly the heavens might be rent asunder from above them (by His Majesty): and the angels glorify the praises of their Lord, and ask for forgiveness for those on the earth. Verily, Allah is the Oft-Forgiving, the Most Merciful.

(148) Verily, We have made it a Qur'an in Arabic that you may be able to understand (its meanings and its admonitions).

(149) And Fir'aun (Pharaoh) proclaimed among his people (saying): "O my people! Is not mine the dominion of Egypt, and these rivers flowing underneath me. See you not then?

(150) And in the alternation of night and day, and the provision (rain) that Allah sends down from the sky, and revives therewith the earth after its death, and in the turning about of the winds (i.e. sometimes towards the east or north, and sometimes towards the south or west sometimes bringing glad tidings of rain etc., and sometimes bringing the torment), are signs for a people who understand.
