An Online dictionary is a digital resource that provides definitions, translations, synonyms, antonyms, and other linguistic information. It is accessible via the internet and can be used on various devices such as computers, tablets, and smartphones. Unlike traditional paper dictionaries, online dictionaries are constantly updated with new words and meanings, ensuring users have access to the most current language information. This makes them an invaluable tool for students, educators, writers, and anyone looking to enhance their vocabulary and language skills.

Online dictionaries offer a range of functionalities that make them highly useful. They often include audio pronunciations, which help users learn the correct way to say words. Many online dictionaries also provide example sentences, showing how words are used in context. Additionally, they may offer translation services, allowing users to find equivalent words in different languages. These features make online dictionaries not only a tool for finding word meanings but also a comprehensive resource for language learning and improvement.

In schools, online dictionaries are typically integrated into the curriculum to support language learning and literacy development. Teachers may use them during lessons to demonstrate word meanings and usage. Students can access online dictionaries on their personal devices or school computers to assist with reading assignments, writing tasks, and language exercises. By incorporating online dictionaries into the classroom, educators can provide students with immediate access to a wealth of linguistic information, fostering a more interactive and engaging learning environment.
