NG

NG is an abbreviation used in different domains to denote several distinct concepts. In geography and politics, NG is the ISO 3166-1 alpha-2 country code for Nigeria, and the corresponding internet country code top-level domain is .ng. The code appears in various datasets and classifications that identify Nigeria; the currency code for the Nigerian naira is NGN, though NG itself is not a currency designation.

In technology and industry, NG commonly stands for next generation. It is used in product names, specifications, and branding to indicate newer versions, architectures, or capabilities relative to earlier generations. The exact meaning of NG in this context depends on the field and the product line.

In linguistics and orthography, ng describes a velar nasal sound found in many languages, including English. The combination of the letters n and g is treated as a digraph representing a single phoneme in phonology and is often written as “ng” in lowercase, though it may appear in uppercase in certain notations or diagrams.

In quality control and manufacturing, NG stands for No Good, signifying an item that fails inspection or does not meet required specifications. This label helps distinguish defective products from those that pass quality checks.

Other uses exist in culture, media, and organizational names, but they are highly context-dependent. Because NG is a generic acronym with multiple legitimate meanings, disambiguation is necessary to determine the intended sense in a given encounter.
