"I used the computer for my work."
Translation:Ik gebruikte de computer voor mijn werk.
Why we say "ik dacht" but here we say "ik gebruikte"?when we put "e" at the end,when we dont?im confused.
"gebruiken" is a weak verb. The past tense is formed by adding -te(n) to the stem.
"denken" is a strong verb. The past tense is formed by changing the vowel of the stem, in this case from e to a. You don't add an -e for singular, only -en for plural.
