Alone means there is nobody else there. You come home, the flat is empty, and you eat alone at the kitchen table with the radio on.
It sits after the verb or the noun — she lives alone, the children were alone — and never in front of a noun: 'an alone child' is wrong, say a child on their own. Alone is a fact; lonely is a feeling, and you can be alone all weekend and perfectly happy. Placed after a noun or pronoun it means only that one: she alone knew the code, the rent alone eats half his wages. Let alone is the phrase to learn — he can't boil an egg, let alone cook dinner — while leave me alone means stop bothering me, and go it alone means doing it without help.

Alone is two words that grew together: Old English eall ān, 'all one', which became al oon in Middle English and then allone. The word once said exactly what it means — completely one, one and nothing else. One later shifted its pronunciation and alone did not, which is why the pair no longer sound like relatives.
