The Arabic word tarweehah (of which Taraaweeh is the plural form) means “a pause for rest.” At the conclusion of each four rakahs, the worshippers sit and pause for a rest for a little while Salaat-ut-Taraaweeh (the Taraaweeh prayers) is a special form of prayer performed at night in the month of Ramadan, in sets of two rak’ahs each, after the Ishaa prayer and before the witr prayer.
Salaat-ut-Taraaweeh is a Sunnah of the Prophet (pbuh) both for men and women. Allah’s Messenger offered this prayer in the mosque during one night of Ramadan and some people joined him. The next day he did the same and more people prayed behind him. The same thing happened during the third night. The believers expected the Prophet to lead them in this prayer again on the fourth night, but he did not show up until Fajr prayer. To explain why he did so, he told them later “I was afraid it would have become obligatory on you, and you may not be able to carry on with it.” (Al-Bukhaaree)
