Quoting Maya Angelou, the couple's latest post read: "Each time a women stands up for herself without knowing it possible, without claiming it, she stands up for all women."
However, their eagle-eyed followers swiftly spotted a mistake.

Maya Angelou was an American poet, singer, civil rights activist and was hailed as a new kind of memoirist - inspiring people around the world as one of the first African-American women who openly discussed their personal life in order to help others. These words, used in The Duchess’ speech on the opening day of the Southern Africa Tour in Nyanga, South Africa, surrounded by the inspiring Mbokobo girls, should always be a reminder that no matter how big or small, your voice has a purpose.
One said: "With your education I'd expect you to know when to use the word woman or women."
Another called the post very "unroyal".
"For a calligraphy person, you sure can’t spell. How unroyal of you," the follower said.
Please correct the typo, it’s unacceptable on an official royal account.
"Typo alert!" screamed another.
Another advised: "Correct your spelling. WOMAN."
"Please correct the typo, it’s unacceptable on an official royal account," said another.
Others accused the couple of trying to steal the limelight from the Duke and Duchess of Cambridge as they embarked on their royal tour of Pakistan.
One said: "I knew she wasn’t gonna stop with these posts, especially when today is the start of the Cambridge Pakistan tour. The Cambridges didn’t do anything to take away from their African tour."
However, some didn't care about the typo and instead looked beyond that to the message contained in the quote.
One follower said: "Really the HATERS are out early. You all missed the message, talking about the grammar. People really need to grow up and stop trying to destroy Meghan, it's really getting old. Thanks Meghan for trying to inspire real women."
