But although ‘the’ has no meaning in itself, “it seems to be able to do things in subtle and miraculous ways,” says Michael Rosen, poet and author. Consider the difference between ‘he scored a goal’ and ‘he scored the goal’. The inclusion of ‘the’ immediately signals something important about that goal. Perhaps it was the only one of the match? Or maybe it was the clincher that won the league? Context very often determines sense.

There are many exceptions regarding the use of the definite article, for example in relation to proper nouns. We wouldn’t expect someone to say ‘the Jonathan’ but it’s not incorrect to say ‘you’re not the Jonathan I thought you were’. And a football commentator might deliberately create a generic vibe by saying, ‘you’ve got the Lampards in midfield’ to mean players like Lampard.

The use of ‘the’ could have increased as trade and manufacture grew in the run-up to the industrial revolution, when we needed to be referential about things and processes. ‘The’ helped distinguish clearly and could act as a quantifier, for example, ‘the slab of butter’.

This could lead to a belief that ‘the’ is a workhorse of English; functional but boring. Yet Rosen rejects that view. While primary school children are taught to use ‘wow’ words, choosing ‘exclaimed’ rather than ‘said’, he doesn’t think any word has more or less ‘wow’ factor than any other; it all depends on how it’s used. “Power in language comes from context... ‘the’ can be a wow word,” he says.

This simplest of words can be used for dramatic effect. At the start of Hamlet, a guard’s utterance of ‘Long live the King’ is soon followed by the apparition of the ghost: ‘Looks it not like the King?’ Who, the audience wonders, does ‘the’ refer to? The living King or a dead King? This kind of ambiguity is the kind of ‘hook’ that writers use to make us quizzical, a bit uneasy even. “‘The’ is doing a lot of work here,” says Rosen.

Deeper meaning

‘The’ can even have philosophical implications. The Austrian philosopher Alexius Meinong said a denoting phrase like ‘the round square’ introduced that object; there was now such a thing. According to Meinong, the word itself created non-existent objects, arguing that there are objects that exist and ones that don’t – but they are all created by language. “‘The’ has a kind of magical property in philosophy,” says Barry C Smith, director of the Institute of Philosophy, University of London.
