Comparison & Degree · just as..., as if..., like..., as...
V+듯이 is a connective ending used to indicate that the action or state in the following clause is performed in the same manner as, or strongly resembles, the action or state described in the preceding clause. It draws a direct comparison, often implying that the first action serves as a model or reference for the second.
This pattern is employed when you want to emphasize that something is happening just like something else, or as if it were that other thing. It's particularly useful for describing actions that are imitative, habitual, or so similar that they evoke the image of the comparison. The nuance often suggests a vivid or observed similarity, rather than a purely hypothetical one. It can be used for both literal comparisons (e.g., doing something exactly as someone else did) and figurative ones (e.g., doing something as easily as breathing).
-듯이 attaches directly to the verb stem, regardless of whether the stem ends in a vowel or a consonant.
Verb stem ending in a vowel: Remove 다, add -듯이.
Verb stem ending in a consonant: Remove 다, add -듯이.
Verb stem ending in ㄹ: Remove 다, add -듯이. The ㄹ remains.
