I bought a Nikon 18-140mm DX lens and I’m confused by the naming on the barrel. I know VR means Vibration Reduction, but I’ve seen it written as “VRm” and wasn’t sure whether the “m” means something specific. Also, what does the “G” designation mean on this lens?

On this lens, “VRm” is most likely just a typo or misreading, not a Nikon designation. The official lens name is AF-S DX NIKKOR 18-140mm f/3.5-5.6G ED VR. In that name, VR stands for Vibration Reduction.
G is Nikon’s designation for a G-type lens, which means the lens does not have an aperture ring on the barrel; aperture is controlled electronically from the camera body.
Other abbreviations you may see for this lens in Nikon’s documentation include:
- DX: designed for Nikon APS-C / DX-format cameras
- AF-S: Silent Wave Motor autofocus
- ED: Extra-low Dispersion glass
So the short answer is:
- VR = Vibration Reduction
- VRm = not a standard Nikon marking here
- G = no aperture ring, aperture controlled by the camera

VRm is just a typo. You can cross reference the annotations on the lens with the official Nikon Page for your lens (AF-S DX NIKKOR 18-140mm f/3.5-5.6G ED VR), which lists the following technology attributes (or tags):
ED - Extra (low) Dispersion Glass
VR - Vibration Reduction
SWM - Silent Wave Motor
IF - Internal-Focusing
A-M - Auto-Manual Mode Support
SIC - Super Integrated Coating
AS - Aspheric Lens Elements
Not all of these attributes/tags will appear on the lens barrel, but they will all be shown on either the official page for the lens or appear in the User Manual for the lens.
The G designation for your lens is not listed as an official Nikon technology attribute on the official lens page, but if you need something of an authoritative definition for it, then according to this page (How to read your lens barrel), it just means the aperture on your lens can only be set using a command dial on your Nikon camera body. There is a group of designations that never appear together (G, D, AI-s, and AI) which may be regarded as a label of the type of aperture control, though some of these also relate to non-aperture-based functions as well.
