Assemblé means assembled (from assembler meaning to bring together). Most commonly this refers to the jumping action which brings the two legs together with one foot in front of the other. The goal being to assemble the legs in the air before landing.

Assemblé appears in the 1895 Dictionnaire de la danse by Desrat but does not appear in the 1787 Dictionnaire de danse, this appearance is congruent with the increased height and variation of jumps that occurred during this period.

Assemblé is pronounced [asɑ̃ble].  A is pronounced like ahhh in English. It is a soft open-mouthed sound, -ssem sounds similar to the beginning of the word somber in English but the m is not as pronounced because the e and m combine to form a nasal vowel so the sound comes out of both the nose and mouth. -blé sounds similar to -blay (like play) in English (without the final y).

In assemblé the dancer brushes or dégagés the leg to the front side or back. This brush is followed almost simultaneously by the dancer pushing up and away from the floor by springing off the supporting foot. The legs meet with one leg crossed in front of the other in a crossed fifth position and then the dancer lands in fifth position plié.

While assemblé is most often an intermediate through advanced movement, young dancers can learn this step traveling forward landing in either parallel or first position.
