It is true that language acquisition is a complex process. Therefore, it is advisable to teach a foreign language at elementary school rather than secondary. According to me, the merits of this notion outnumbered its demerits.
To embark on, there are numerous benefits of teaching a foreign language to children at an early age. First of all, children have a receptive mind with good grasping power. This age is the learning stage of life. Whatever is learned in childhood, can remember longer in life. Besides that, children are less egoistic and are not afraid of committing a mistake in learning. As failures are the pillars of success while continuous practicing they may attain a reasonable level of language. Undoubtedly, a language consists of different dialects, grammatical rules, intonations, denotation, functions syntax, and style. By practicing these, a child can possess unmatchable linguistic skills. Secondly, everyone is in a mad race to fly board in this modern scenario, and possession of a foreign language equips them to communicate freely for easy survival. Moreover, polished communication skills have become a need for the hour of the cutthroat competitive world.
However, it is also a fact that going to school, doing homework, and taking part in extra-curricular activities is itself a time-consuming activity for students. If they are exposed to regular language teaching sessions that will make them pressurized and psychological illness. This type of burden will hamper their physical, mental, and psychological growth.
To conclude, even though, teaching a foreign language may aggravate their existing burden preparing the young mind for further survival has become mandatory by imparting linguistic skills.
