esteem: [15] Esteem and estimate [16] are fairly open about their relationship, but there is another, more heavily disguised member of the family: aim. All three come ultimately from Latin aestimāre. Estimate was a straightforward borrowing from the Latin past participle aestimātus, but esteem came via Old French estimer, and aim from the reduced Old French form esmer. Originally, esteem meant much the same as estimate does: ‘evaluate, assess’. But as early as the 16th century it had passed into ‘think highly of’ (a semantic development interestingly paralleled in the 20th century by rate). => aim, estimate
