blurring
ぼやける
解説 Definition
blurring は blur（ぼやける、ぼやけさせる）の現在分詞・動名詞です。写真・映像・文字・輪郭などがはっきり見えなくなる、または意図的に不鮮明にする場合に使われます。
The present participle or gerund of “blur,” describing something becoming visually unclear or the act of making an image, outline, light, or distinction less sharp and definite.
覚え方のコツ Memory Tip
原形 blur は短い母音の後に子音 r が一つあるため、-ing を付ける際に r を重ねて blurring となります。発音でも blur の母音と r のまとまりを保ちます。blurring the background は意図的にぼかす用法、the image is blurring は自然にぼやける用法です。
Connect blurring with the base verb blur. Because blur ends in a stressed vowel-plus-consonant pattern, the final r is doubled before -ing: blur becomes blurring, not “bluring.” Picture two common situations. In “the image is blurring,” the image is becoming unclear, perhaps because the camera is moving. In “blurring the background,” someone deliberately makes the background less sharp. The idea can also be figurative, as in blurring the distinction between two categories, where a boundary becomes harder to recognize.

blurring の語源・成り立ち Etymology
「blur」は中オランダ語のblurren（ぼかす）に由来します。語根「blur」に接尾辞「-ing」が付き、動作の進行を表します。同語根のblurry（ぼやけた）やblear（目のかすむ）と繋がり、視覚が混ざる様子から「輪郭がはっきりしなくなる」という意味が納得できます。
Blurring is formed from blur by doubling the final r and adding -ing. Blur entered English with the sense of a smear, stain, or obscuring mark, but its more distant origin is uncertain; proposed connections with similar Germanic words are not fully established. The verb came to describe making something indistinct or becoming indistinct, first visually and later figuratively, as when boundaries or distinctions lose their clarity.
