How access term name by object? I want to load parent term name by tid .I am using this 

$term = \Drupal::entityTypeManager()-&gt;getStorage('taxonomy_term')-&gt;loadParents($tid);
kint($term);


This return a object which is my parent term but I am not able to access term name by this object. Please check attached screenshot of kint($term).
You should get the name with the getName method.
In your case :

$term[1]-&gt;getName();
$term-&gt;getName();


If not, you can load the term and after get the name:

$term = Term::load($term[1]-&gt;id());
$term-&gt;getName();
