【Praise】 , 【laud】 ,  【acclaim】 ,  【extol】 ,  【eulogize】  mean to express approbation or esteem.

【Praise】 often implies no more than warmly expressed commendation. When specifically referred to persons, it frequently suggests the judgment of a superior. However, it is also used in reference to God or a god or to a saint; then it implies glorification by such acts of homage as song or prayer.

【Laud】 implies high, sometimes excessive, 【praise】 .

【Acclaim】 usually suggests enthusiastic and public expression of approval.

【Extol】 retains its original implication of lifting up or raising and suggests 【praise】 that exalts or magnifies. It is often used when a contrast between approbation or esteem and their opposites is enforced.

【Eulogize】 , sometimes interchangeable with  【extol】 , may differ from it in implying formality both in the method and in the occasion; very frequently it suggests a set composition or oration (eulogy ) suitable for a funeral or testimonial.
