Expert writing Tips

Best practice

Avoid using the phrase "more thinner" in formal writing. Opt for "thinner" or "more thin" depending on the context for grammatical correctness.

Common error

Using both "more" and the "-er" suffix to indicate a comparative degree is redundant. Instead of "more thinner", choose either the "-er" suffix ("thinner") or use "more" with the base adjective ("more thin"), but not both.

Linguistic Context

The phrase "more thinner" functions as a comparative, attempting to indicate a greater degree of thinness. However, it's grammatically flawed, as noted by Ludwig AI, because it combines both the "more" modifier and the "-er" suffix, which is redundant in standard English.

In summary, while the phrase "more thinner" appears in various sources, it is considered grammatically incorrect. As Ludwig AI explains, the correct forms are "thinner" or "more thin".

FAQs

Is "more thinner" grammatically correct?

No, "more thinner" is grammatically incorrect. The correct comparative forms are "thinner" or "more thin". Using both "more" and the "-er" suffix is redundant.

What's a better way to say "more thinner"?

Instead of "more thinner", use the comparative adjective "thinner" or the phrase "more thin". For example, "This fabric is "thinner"" or "This layer needs to be "more thin"".

When should I use "thinner" versus "more thin"?

For most adjectives ending in a consonant followed by 'y' (like 'thin,' which doesn't end in 'y'), the '-er' suffix (resulting in '"thinner"') is generally preferred. You might use "more thin" for emphasis or in specific stylistic contexts, but "thinner" is usually more concise.

Are there other adjectives that shouldn't be used with "more"?

Yes, many short adjectives that already have comparative forms with '-er' should not be used with "more". Examples include "smaller", "larger", "faster", and "shorter". Using "more" with these is typically considered grammatically incorrect.
