X as in Xanthophyll which is what makes autumn leaves turn yellow.

"Xanthophyll". Yup, first word that popped in my head. ;-)

Xanthopetal

My MIL suffered from a rare genetic disorder called PXE: Pseudoxanthoma Elasticum. It's a connective tissue disorder, one effect of which was to give her this yellowish colored bumpy skin on her armpits and neck that looked sort of like chicken skin...thus the "xantho" in the name.

Xenophobic not- photo credit to my young granddaughter

Xanthophobia ...good thing I don't have it, it's taking over my back yard.

Shame on these two, committing an X-rated act right here for all to see

Ha I forgot about my x-rated picture! Maybe I'll save it for the next "x" day...birds do it, bees do it, even educated fleas do it...

XXX... we have a Naked Lady here...

OK...take you time here

Take the letter X and say it out loud

Now, stretch the word out, say it long!

xerophyte near Corona Arch. (A plant that needs very little water)

X-Acto knife.

Cross stitch - lots of little x’s

The smaller tree says it all.

This was a real challenge, for sure. Mine is a picture of my Scrabble game with two of the most popular words beginning with X.

I'm very impressed with all of the Xs today - what a creative group we have here!

I agree Dawn! And eggs ? Hilarious!

Apologize for terrible pictures Scanner isn't working and tried to take with camera from photo album.

The fortifications of Xi'an (Chinese: 西安城墙), also known as Xi'an City Wall, in Xi'an, an ancient capital of China, represent one of the oldest, largest and best preserved Chinese city walls.

XRAY - Elvira's spine. Dachshund's have spine problems but her's was OK.

There's an X on the door of the garden shed. This was a difficult one.

Great job, everyone!

I know! So unexpected the imagination and variety.

Everyone has come through with flying colors on the hardest letter of all...it'll make the "z" in a couple of days a piece of cake! Zabaglione???

I bought this to send to a friend whose name begins with X, a difficult initial.

threejs Please read the guidelines at the top of the page in Annie's first post.

I did give credit to google. It was a stock picture, one of many. The only other picture I have is of a family member playing the xylophone, and as I wasn’t born I can’t give credit to the photographer whom I did not know. Oh, after being at the table twenty years I do read all the rules and regulations.

So it is off the internet?

Carry on..................

Yeah, threejs, photos off the internet are not within the guidelines for these threads, especially copywritten and watermarked photos such as posted above. I'd rather you posted a family photo and be unsure of the photographer than an internet photo as at least that would be more personal and meaningful to you.
