"Explain" is to give a detailed account of why or how; "tell" is to communicate information or a story.
To make something clear or understandable by giving reasons, details, or instructions.
Can you explain how this machine works? I have never used it before.
The teacher explained the grammar rule three times until everyone understood.
She explained why she was late, but I couldn't really follow her reasoning.
To communicate information, facts, instructions, or stories to someone.
Tell me about your trip to Mexico. How was it?
He told me that the meeting was canceled.
She told her children a bedtime story every night.
Common mistake
"Explain me" is incorrect in English: "explain" always needs "to" before the pronoun ("explain TO me", "explain it to me"). "Tell" goes directly: "tell me", "tell her". And to describe a process, use "explain how it works", not "tell how it works".
Trick to remember it
Quick rule
"Tell" + person directly. "Explain" + to + person. Tell = simple information. Explain = reasons, instructions, understanding.
Did you know?
"Explain" comes from Latin "explanare", literally "to flatten" (ex- = out, planus = flat). The original idea was "to make something level, free of obstacles for understanding". It is the same root as "plain" (flat, clear, simple) in English. When you explain something, you are mentally "flattening" it to make it easier to understand, the spatial metaphor of clearing the path to understanding is embedded in the word itself.
Exercise 1 · Pick the right one
Can you _____ me how the coffee machine works? I can't figure it out.
Exercise 2 · Pick the right one
Can you _____ me the time? I left my phone at home.
Exercise 3 · Form the word
"Say" is to produce words; "mean" is the intention or meaning behind them.
Both mean 'to say', but 'tell' always needs to know who receives the message.
"Above" is at a higher level without contact; "over" implies covering, movement, or crossing.
"Actually" corrects or contrasts an assumption; "really" intensifies or confirms.
