Polissemia is a linguistic phenomenon where a single word has multiple meanings. For example, in English, the word 'run' can mean to move swiftly using one's feet, to operate a machine, to compete in a race, or even to flow like a liquid. Choose a word in English that is polisemic, explain its different meanings and provide a short sentence for each meaning, demonstrating the word's use in context. Additionally, discuss the potential challenges that learners of English might face when encountering polisemic words and suggest a strategy to help them navigate through these challenges effectively.
