ca·tal·y·sis

 (kə-tăl′ĭ-sĭs)
n. pl. ca·tal·y·ses (-sēz′)

[Greek katalusis, dissolution, from katalūein, to dissolve : kata-, intensive pref.; see cata- + lūein, to loosen; see leu- in Indo-European roots.]

cat′a·lyt′ic (kăt′l-ĭt′ĭk) adj.
cat′a·lyt′i·cal·ly adv.

catalysis

(kəˈtælɪsɪs)
n, pl -ses (-ˌsiːz)
(Chemistry) the acceleration of a chemical reaction by the action of a catalyst
[C17: from New Latin, from Greek katalusis, from kataluein to dissolve]

ca•tal•y•sis

(kəˈtæl ə sɪs)

n., pl. -ses (-ˌsiz)
1. the causing or accelerating of a chemical change by the addition of a catalyst.
2. an action between two or more persons or forces, initiated by an agent remaining unaffected by the action.
[1645–55; < New Latin < Greek katálȳsis dissolution =kataly(ein) to dissolve (kata- cata- + lyein to loosen) + -sis -sis]

catalysis

Rare. the process of decay or deterioration. See also change.
