The phrasal verb "tell apart" is predominantly used in informal contexts, though it can appear in semi-formal communications, particularly in contexts such as education or discussions that involve explanations. "Tell apart" refers to the ability to distinguish the difference between two or more similar items or people. It commonly emerges in scenarios where differentiation is challenging, for example, when identifying identical twins or distinguishing between similar sounding words. In more formal situations, phrases like "distinguish between" might be preferred. "Tell apart" is not typically used in technical or scientific writing, where more precise language is favored. It's often utilized in spoken language, as well as in written formats aiming to maintain a conversational tone.
