Translation

Definition
To activate something means to make it start working or become operational. This verb is commonly used in contexts involving devices, systems, features, or processes that need to be turned on or set in motion. For example, you might activate a new credit card by calling a phone number, activate an alarm system before leaving home, or activate a software license with a product key. The word can also apply to abstract concepts, such as activating a plan or a person's potential. In everyday language, 'activate' often implies a deliberate action that initiates a function or state. It is the opposite of 'deactivate' and is frequently found in technical, administrative, and motivational settings. This word has other meanings, such as in chemistry (making a substance reactive) or physics (making a material radioactive), but the most common and practical use for learners is the one described here.
