I was just studying about wetting on surface chemistry and I'm not sure what does omniphilic and omniphobic means? Can someone please explain?

"For nonwater liquids, the term lyophilic is used for low contact angle conditions and lyophobic is used when higher contact angles result. Similarly, the terms omniphobic and omniphilic apply to both polar and apolar liquids." -https://en.wikipedia.org/wiki/Wetting

This Wikipedia excerpt clearly explains that these are more general terms covering all liquids, not just water.

Omniphobic/philic means it repels/attracts "all" liquids. I use "all" in quotations because omniohobic surfaces are usually highly fluoridated surfaces and they won't repel highly fluorinated liquids as well as more typical liquids.

Not sure about omniphilic surfaces.

High contact angle implies a high degree of repulsion of a liquid by the surface it's resting on.
