Applause
Applause (Latin applaudere, to strike upon, clap) is primarily a form of ovation by the act of clapping, or striking the palms of the hands together, in order to create noise. Audiences usually applaud after a performance, such as a musical concert, speech, or play, as a sign of enjoyment and approval. Clapping nowadays is very popular and in most countries audience members clap their hands at random to produce a constant noise. It tends to synchronize naturally to a weak degree; in Russia, Norway and many northern and eastern European countries synchronized clapping is more popular than random clapping.
Applause (noun)
The act of applauding; approbation and praise publicly expressed by the clapping of hands, stamping or tapping of the feet, acclamation, huzzas, or other means; marked commendation.
