You might have seen people on social media posting pictures of semicolons drawn or tattooed on their wrists or elsewhere on their bodies.

No, they're not grammar pedants - there's actually a much more touching reason behind it.

Non-profit mental health organisation, The Semicolon Project, is encouraging anyone who has been through depression, anxiety, or had suicidal thoughts, to draw a semicolon on their wrist.

While some have settled for a temporary 'tat' drawn on in biro, others have committed by getting inked.

What's the story behind the semicolon tattoo craze that's sweeping the internet?

Why this particular punctuation mark? The Project Semicolon website says that: "A semicolon represents a sentence the author could have ended, but chose not to.

"That author is you and the sentence is your life."

And anyone can take part. The project is a 'faith-based movement dedicated to presenting hope and love for those who are struggling with depression, suicide, addiction and self-injury."

Participants in the project have been posting pictures of their tats on social media - and some have added their own, touching stories.

I will always suffer from depression but the self harm && suicide ideation has finally ceased. The sentence of my life is not over; #semicolonproject"

Instagram user lonigene commented: A semicolon is used when an author could have chosen to end their sentence, but chose not to.

"You are the author, the sentence is your life. For anyone suffering from depression, anxiety, self harm, contemplating suicide, you are not alone. You are worthy. You are loved."
