Despite at times the gestures are not related to the meaning of the word, the fact that the gestures are enough to make the second language learner remember the word and meaning is imminent. However, on the contrary, it only works for the case of congruent gestures and not for incongruent gestures. Besides that, sometimes, the hand movements and body movements might be too much of visual information, which makes it distracting for the learner to capture the meaning of the word. Generally, the input from speech and gestures facilitates second language learning only up to the semantic level and not the concept.

With this, we come to question if this method is applicable for the use of learning any second language. As stated above, languages are culture specific, be it sign language or just language, this means that different cultures have got different interpretations of different gestures. For instance, the Okay or OK sign is mostly considered as a good hand gesture. The hand gesture is used by curling the index finger over the thumb and the remaining fingers extended above them. This means that everything is good or well. Also, this sign is usually used by divers to indicate all is well or OK as the thumbs up sign means ascending. However, in Latin America and France it is considered as an insulting sign as it is thought to mean your anus and has negative connotations attached to it. In Australia, it means zero and in Germany it may mean a job well done or an offensive insult depending on the region you visit. In New Zealand, this sign is not used much and considered a cheap way of saying OK. In Turkey, the OK sign means one is a homosexual.

Even so, gestures are still useful for second langugae learners because they aid social interaction by streamlining action understanding between speakers besides improving language comprehension. According to Oztop, Wolpert and Kawato (2005), the imitative motor helps listeners anticipate other people’s actions better by genereting forward models. With this, gestures are important in aiding a person when learning a new language.
