Questions & Answers about Deze auto heeft een oplaadbare accu.
How exactly is the adjective oplaadbare formed using the -baar suffix?
The base verb is the separable verb opladen (to charge). To make an adjective meaning "able to be charged", you take the entire verb stem including the prefix, which is oplaad, and attach the suffix -baar. This creates the base adjective oplaadbaar.
Since the suffix is -baar, why is it spelled with a single 'a' in oplaadbare?
This is a great refresher on the Dutch open syllable rule. When the adjective ending -e is added to oplaadbaar, the syllables become op-laad-ba-re. Because the ba syllable now ends in a vowel (an open syllable), one a is dropped to maintain the long vowel sound without needing double letters.
Why does oplaadbaar get the -e ending here?
It is acting as an attributive adjective describing the noun accu. Since accu is a de-word, adjectives modifying it get an -e ending. The only time an adjective after een does not get an -e ending is when it modifies a het-word.
Why use accu instead of batterij for "battery"?
