We think in words and our words have a cultural bias. Learning a language other than our first spoken connects us with a different way of making meaning. In so doing, we learn to respect, empathise and accept cultural differences.
We also explore the differences in things we may take for granted in vocabulary, grammar and syntax (not all languages have only five vowels, tense, subject/verb/object structures).
Learning another language promotes global citizenship – and awareness of the evolution of language over time in different cultures. When we learn a language we do so in the context of a culture’s customs: food, society, currency, geography, history, religion/s.
Neurologically, learning a language is akin to learning music: it expands the neural networks and opens more connectivity to new concepts.
