ば～程(ほど)The more…the more

ば～ほど is a combination of the conjunction particle ば, and the noun ほど. It is used in a similar way to 'the more ~ the more' in English. Literally, it just highlights that 'if it is (A), then the limit of (A) will be controlled only by its extent'.

To use ば～ほど, ば will be paired with the hypothetical form of any verb/い-Adjective (or noun/な-Adjective with なら on the end), before the same word will be repeated in its attributive form. After this, a (B) part of the sentence will highlight what the expected result of (A) is.

As である (the formal version of だ) may replace な with な-Adjectives (or なら with nouns), sometimes である will be used instead of な/なら, in regard to both nouns and な-Adjectives.

Caution

When this expression is used with する verbs, the noun that する is linked to in the ば part of the sentence does not need to be repeated in the ほど part.

Fun Fact

Sometimes, the ば 'hypothetical' part of the sentence will be omitted altogether, leaving ほど to perform a similar function by itself.
