If you haven’t yet figured out what’s different in both the words, it is just the extra ‘e’. Yet, there is no similarity in the meaning of homogenous and homogeneous.

In this Grammar.com article, let us understand some important differences with appropriate examples for each of the words.

Homogeneous

During our chemistry lessons at school, we encountered this word more than often – “two substances having homogeneous characteristics…. “

The word means similar or uniform. Two things, persons or places having similar characteristics are referred to as homogeneous. The opposite (antonym) word of homogeneous is heterogeneous.

Homogeneous is an adjective and finds it roots from the Greek homos (same) + genos (kind). The word found wide usage starting from the 1960s. It is pronounced as ho-mo-jeen-i-yes and has 5 syllables in total.

Some common examples of usage


Homogeneous mixture – If a mixture has more than one component which cannot be separately identified by seeing the mixture, it is called as a homogenous mixture. For example, cake batter, chocolate syrup, milk, tea etc…

Homogeneous group – A group (in an educational setting) having students with similar instructional levels, so that they can work on the areas of their strength and interests. They are also called as ability-level groups.

Homogenous

Well, if you dint know this word – just don’t learn it – it is obsolete anyway. But if you have heard or read about it somewhere, let me tell you that it was used until the 19 th century to talk about biological or genetic similarity. The new term used for this purpose is homologous.

Homogenous has its roots from the English homo (same) + genos (race or kind) + ous. It is pronounced as ho-mah-je-nus with 4 syllables. Here are examples of possible earlier usage,

However, we would recommend you to not use the word. Just stick to homogeneous with the extra ‘e’.

To summarise,

Earlier, homogenous was used as a scientific term, mainly in biology, but now it is almost obsolete, being replaced by homologous. Whereas, homogeneous is a common word, very much in use and means having similar or comparable characteristics.

    Oh my gosh, please stop saying "impact". The implant is not crashing into his body; it is having an effect or influence on his body. I don't know why such nonsensical jargon is being propagated by supposedly learned platforms such as yours, let alone becoming more popular at all.

      The point is that he should've used it 0 times.

      you do realize impact has more than one meaning? Either to come into forceable contact with an object. Or to have a strong effect on someone or something. Which is exactly what you suggest. For example you could say, "My phone has such a strong impact on my life I can't live without it." Or, "The book I read three years ago made such an impact on my perception that I now don't judge people as much as I used to." Or, "I thought my new wife was going to be more of an impact than my ex. But these past few years have proven otherwise."

      And you do realize that it is jargon that is proscribed by almost every writing institution and style guide out there? Nevertheless, even in the jargon sense, your first example of "My phone has such a strong impact on my life, I can't live without it" clearly shows that people don't realize the grammatical mistakes they're making with it as well. If "impact" means "strong/violent/marked effect", then saying "strong impact" is redundant and shows that the person saying it doesn't understand what the word means. This is why the word is proscribed everywhere; there's absolutely no reason to use it when saying "effect" will do just fine and doesn't have the jargon label associated with it.

      The irony of you coming to grammar.com to make fun of people advocating for proper grammar seems to be completely lost on you. I really have to wonder why you're coming here then.
