※ 無害、天真 ※

無害的概念是 "單純"、"天真無邪"、"自然"，可用嬰兒去聯想。

innocent (a) 天真無邪的
(MW) lacking or reflecting a lack of sophistication, guile, or
self-consciousness: ARTLESS, INGENUOUS
[衍] innocence (n)

innocuous (a) 無害的

hostility: INOFFENSIVE
[源] in- (not) + noc- (harm)，不造成傷害。
[例] His innocuous remarks in the political meeting aroused other
colleagues' agreement.

naive (a) 天真的
(MW) marked by unaffected (不做作的) simplicity: ARTLESS, INGENUOUS
[源] 法文字，注意發音。na- 來自nat- (= born)，剛出生的嬰兒是 "天真無邪的"。
[衍] naivete (n) the quality or state of being naive
[解] 作 "天真的" 解為正面意涵。另一個意思是 "幼稚的"、"容易上當的"：
naive (a) deficient (缺乏的) in worldly wisdom or informed judgment
especially: CREDULOUS，為負面意涵。

ingenuous (a) 天真的
(MW) showing innocent or childlike simplicity and candidness <her
ingenuous thirst for experience>

big city.
[解] 不要和 ingenious (a) marked by originality, resourcefulness, and
cleverness in conception or execution <an ingenious contraption>
"聰明的、精巧的" 搞混。可用 genius (n) "天才" 來記此字。
[記] 你 (U) 天真我 (I) 聰明。

特別注意 -less 作字尾時是 without "完全沒有" 的意思，不是 "較少"
(less 為單字的意思)，可把 -less 看做是 "not" 的轉折訊號。

guileless (a) 天真無邪的
(MW) INNOCENT, NAIVE
[衍] guile (n) deceitful cunning (心機): DUPLICITY "欺騙"
[例] He is a guileless man who often guides readers to improve
their effectiveness in speech and writing.
[解] guile (負面) + less (without) = guileless (正面)

artless (a) 單純的 (= guileless)
(MW) free from (沒有) guile or craft: sincerely simple <an artless
young woman>
[衍] art (n) skill acquired by experience, study, or observation
<the art of making friends>
[衍] 反義字：artful (a) adroit (熟練的) in attaining an end usually by
insinuating (暗示) or indirect means: WILY <an artful cross-examiner
(交叉盤問者)>，"心機重的"、"狡猾的"，常用於負面意涵。
[例] His simple artless charm won us over instantly.
[解] 藝術 (art) 需要 "技巧"，引申為 "手腕"，artless 同義字是 unskillful，
不加矯飾。art (負面) + less (without) = artless (正面)。
