-genic
suffix
Used to form adjectives referring to the production or causation of something, often in scientific or medical contexts. Derived from the Greek root ‘-genēs,’ meaning ‘born’ or ‘produced.’ Examples include ‘carcinogenic’ (causing cancer), ‘photogenic’ (producing pleasing photos), and ‘iatrogenic’ (caused by medical treatment).
Example Sentences
Carcinogenic substances can initiate or promote the development of cancer in living organisms.
Photogenic individuals tend to appear visually appealing in photographs under a variety of lighting conditions.
Iatrogenic complications are those inadvertently caused by medical procedures or treatments.
Endogenic geological processes, such as volcanic eruptions and plate tectonics, originate within Earth’s interior.
Allergenic foods trigger immune responses in sensitive individuals, often leading to hives or respiratory problems.
Psychogenic disorders, like certain cases of chronic pain, stem from psychological or emotional factors rather than direct physical causes.
Geogenic influences, including mineral composition in soils and rock formations, can significantly affect water quality and local ecosystems.
Understanding the distinctions between endogenic and exogenic forces is crucial in geology, as the former arise from Earth’s interior (like magma formation), while the latter involve external agents such as wind, water, and temperature changes.

How to Use
A suffix meaning producing, causing, or generating something.Words ending in “-genic” often point to something causing or producing a specified effect, quality, or condition. For example, “carcinogenic” describes substances that produce or cause cancer, while “photogenic” pertains to generating a pleasing visual effect in photos. When you see “-genic,” look for the root to identify what’s being generated or caused: “carcino” (cancer), “photo” (light). In technical or scientific contexts, this suffix efficiently denotes causation or production, such as “allergenic” (producing an allergic reaction) or “pathogenic” (causing disease). If you’re writing formally, be sure to clarify the specific effect or condition that is being generated, especially for complex or less common words. Meanwhile, in general usage, “-genic” can subtly convey “has the potential to produce” or “gives rise to.”
Alternatives
If you want simpler wording, replace “-genic” expressions with phrases like “causing,” “leading to,” or “giving rise to.” Instead of “carcinogenic,” you might say “cancer-causing.” Rather than “photogenic,” you could say “looks great in pictures.” This can make your writing or speech more accessible to general audiences. However, the short precision of “-genic” is often helpful in fields like medicine, biology, or photography, where each term carries a specific, recognized meaning. Decide which approach—technical or plain language—best suits your context and audience. Using these alternative phrases maintains clarity while avoiding specialized terminology if your readers may not be familiar with it.
Writing
In formal or technical writing, “-genic” terms quickly communicate an object or substance’s capability to generate a certain effect. For example, “neurogenic” (originating in the nerves) and “iatrogenic” (caused by medical treatment) signal precise causes without lengthy explanations. If you’re writing for a broad audience, include brief definitions to keep everyone informed. As always, assess whether your readers will likely understand “-genic.” In specialized fields—like medical, biological, or environmental studies—such terminology can be appropriate and efficient. Just remember to define unusual or niche uses so that your work remains accessible and transparent.
Casual Conversation
Everyday conversation rarely dives into “-genic” words, except maybe “photogenic.” When you do use such terms, be prepared to clarify. Saying “this chemical is carcinogenic” might need the follow-up “it causes cancer.” The suffix can sound formal, so opt for plain language if you’re aiming for a friendlier tone—“causes allergies” instead of “allergenic,” for example. Still, knowing “-genic” helps you decode more complex terms in news articles, health warnings, or scientific reads. This familiarity makes it easier to understand what specific conditions or effects are at play, even if you choose simpler words day to day.
Etymology
The suffix “-genic” traces back to the Greek “-genēs,” meaning “born of” or “produced by,” which is related to “genein,” meaning “to produce.” The concept of origination or creation carried forward into Latin and eventually entered English through scientific terminology. Over time, “-genic” became a clear marker of something that generates or causes a particular condition or effect. Its Greek and Latin roots underscore the consistent thread of “bringing into being,” an idea that remains central whether discussing disease causation, photographic properties, or any field where origin and effect are paramount.
