Explanation at your level:
A thorn is a sharp part of a plant. Think of a rose. If you touch the stem, it might hurt. That sharp part is a thorn. Be careful when you pick flowers!
A thorn is a small, sharp spike on a plant. Plants like roses have thorns to protect themselves. If you are not careful, a thorn can prick your skin and it might hurt a little bit.
A thorn is a woody, sharp-pointed outgrowth on a plant. We often use the word when talking about gardening or nature. Figuratively, we say someone is a 'thorn in my side' if they are annoying us for a long time.
Beyond the literal botanical definition, thorn is frequently used in idiomatic expressions to describe persistent irritation. It implies a sense of discomfort that is hard to ignore, much like a physical prick from a plant.
In advanced usage, thorn acts as a powerful metaphor for systemic issues or individuals who impede progress. It evokes imagery of pain and defense, often used in political or literary analysis to describe a lingering, problematic element within a larger structure.
The etymological depth of thorn connects it to ancient Germanic roots, including the Runic alphabet. In literature, it often carries symbolic weight, representing the duality of beauty and danger—the 'rose and the thorn' motif. Mastery of this word involves understanding its transition from a physical botanical term to a nuanced descriptor of psychological and social friction.

Hey there! Let's talk about the word thorn. At its simplest, it is that sharp, pointy bit you find on plants like roses or cacti. Nature uses them as a defense mechanism to keep hungry animals from munching on the plant.
But wait, there is more! We also use thorn in a metaphorical way. If someone says, "He is a thorn in my side," they don't mean he is literally a plant part. They mean that person is a constant source of trouble, frustration, or annoyance. It is a very vivid way to describe something that 'pricks' at your peace of mind.
The word thorn has incredibly deep roots—pun intended! It comes from the Old English word thorn, which shares the same Germanic ancestors as the Old Norse thorn and the German Dorn.
Historically, the word was associated with the Thorn rune in the Runic alphabet, which actually represented the 'th' sound. It has been used in English literature for centuries, often appearing in religious texts and folklore, usually symbolizing both protection and pain. It is one of those rare words that has kept its spelling and meaning remarkably consistent for over a thousand years.
You will mostly hear thorn in contexts involving gardening, nature, or biology. Phrases like sharp thorns or prickly thorns are very common in everyday conversation.
When used figuratively, it is almost always part of the idiom a thorn in one's side. It is a slightly dramatic word, so you wouldn't use it for a minor inconvenience like a missed bus. You save it for persistent, long-term problems that just won't go away, like a difficult coworker or a recurring technical bug.
1. A thorn in one's side: Someone or something that causes constant annoyance. Example: His constant complaining has become a thorn in my side.
2. To be on thorns: To be in a state of anxiety or suspense. Example: I was on thorns waiting for the exam results.
3. No rose without a thorn: Every good thing has a downside. Example: The new job pays well, but there is no rose without a thorn.
4. Crown of thorns: A historical/religious reference to a painful headpiece. Example: The painting depicted the crown of thorns.
5. Thorn in the flesh: Similar to a thorn in the side, a persistent irritation. Example: That tax bill is a thorn in the flesh for my business.
Thorn is a countable noun. The plural form is simply thorns. You will typically see it used with articles like 'a' or 'the' (e.g., "Watch out for the thorn").
Pronunciation-wise, it is a single syllable. The IPA is /θɔːrn/ in British English and /θɔːrn/ in American English, though the 'r' is more pronounced in the US. It rhymes with born, corn, horn, morn, and torn. The stress is always on the single syllable, making it very straightforward to say.
