Some compound words (like bus rapid transit, dog whistle, or identity theft) don’t appear on the drop-down list when you enter them into the search window. If a compound term doesn’t appear in the drop-down list, try entering the term into the search window and then hit the search button (instead of the “enter” key). Alternatively, begin searches for compound terms with a quotation mark.

pen·sive (pĕnsĭv)
Share:
adj.
1. Engaged in deep and serious thought.
2. Showing or expressing deep, often melancholy thought: a pensive look.

[Middle English pensif, from Old French, from penser, to think, from Latin pēnsāre, frequentative of pendere, to weigh; see (s)pen- in the Appendix of Indo-European roots.]

pensive·ly adv.
pensive·ness n.

Synonyms: pensive, contemplative, reflective, meditative, thoughtful
These adjectives mean characterized by or disposed to deep or serious thought. Pensive often connotes a wistful, dreamy, or sad quality: "while pensive poets painful vigils keep" (Alexander Pope).
Contemplative implies slow directed consideration, often with conscious intent of achieving better understanding or spiritual or aesthetic enrichment: "[He] had envisioned an actual grove of academe through which scholars young and old might take contemplative strolls" (Tom Wolfe).
Reflective suggests careful analytical deliberation, as in reappraising past experience: "She ... is as wise as if she'd been on this earth for eighty years. Her nature is reflectivenot all over the map, like mine" (Alice Munro).
Meditative implies earnest sustained thought: "She sat with her shoulders rounded in some clearly deepening meditative privacy and forgot me" (E.L. Doctorow).
Thoughtful can refer to absorption in thought or to the habit of reflection and circumspection: "I had spoken at once ... to Silvius about our departure, and we talked the matter over, for he was a thoughtful and intelligent child, and children have a wisdom of their own" (Ursula K. Le Guin).
