What kind of verb is the word 'seems' in the sentence: 'She seems sad today.''?

• She seems sad today.
- এখানে 'seems' কোন কাজ সম্পাদন করছে না।
- এটি subject এর অবস্থা বোঝাচ্ছে।
- তাই 'seems' এখানে Linking verb/ Copulative verb: 

• Linking verb/ Copulative verb: 
- যে সকল verb সাধারণত subject ও Subjective complement এর মধ্যে যোগসূত্র স্থাপন করে তাদেরকে Linking verb/ Copulative verb বলে।
- Linking verb-এর complement হিসেবে সাধারণত adjective বসে৷
- Subject এবং subjective complement এর মধ্যবর্তী verb কে linking/Copulative verb বলে৷
- অবশ্যই মনে রাখতে হবে - Linking/copulative verb হচ্ছে actionless.
- adverbs can be used before linking verbs if they describe the linking verb and not the subject. 

• Linking verbs are verbs that don’t show an action but rather describe the subject. While verbs like walk or jump represent an action, linking verbs like be or seem add more details to the subject, such as “he seems nice” or “she is an architect.” 

• Linking verbs do not show an action—or more accurately, the only action they show is merely existing. Linking verbs simply explain the state of the subject, such as what it is or how it looks.

Examples:
- He became a doctor.
- My coffee remains hot.
- The car looks fast.
