Correct sentence:
It is an oryx's shadow.
Shorter (with a contraction):
It's an oryx's shadow.
Another way to say it:
It is the shadow of an oryx.
Why this is correct (easy steps):
- Start with a big letter: "It".
- Use "is" (or the contraction "'s") to say what something is.
- Use an apostrophe + s ("'s") to show the shadow belongs to the oryx: "oryx's shadow."
- End the sentence with a period.
Extra tip: "Oryx" is spelled O-R-Y-X. Nice sentence!
