London — Meghan Markle is reportedly receiving etiquette lessons in preparation for joining the royal family after marrying Prince Harry later this year.

The 36-year-old actress will become a member of the famous family when she ties the knot with Prince Harry in May this year, and whilst she won't become Princess Meghan - as that title is reserved for blood relatives of the monarch - she will still be expected to follow a particular set of etiquette rules.

According to sources, the former 'Suits' actress is learning skills such as table manners, how to dress, how to socialise with foreign diplomats, and how to climb out of a vehicle with "royal grace".

A source said: "Meghan is on a crash course with a trusted coach used by the royals. 

"First on the list is silver service - she must be able to tell a fish knife from her butter knife, know how to handle seafood, drink soup and so on.

"There'll be no stone unturned as in less than 12 weeks all eyes will be on her - there is no room for error."

Meghan is also reportedly taking elocution lessons to soften her American accent, and will be expected to learn British terminology so as to avoid potential gaffes over Americanisms.

The source added to the Daily Star newspaper: "Elocution lessons will also feature. Meghan's American twang will be softened and toned down. But more essential is her switching to British terminology - she simply cannot be 'taking out the trash' and 'wearing pants'.

"It's the fine tuning needed to ensure she's not lost in translation. Harry has been brought up living and breathing all this. He has a lifetime of nurturing and breeding behind him but Meghan has a matter of weeks to learn what she needs to be accepted at the royal court.

"If she was left without guidance, the marriage would begin in the same vein as Diana and Charles - with the bride feeling helpless and alone."
