めく

めく is a fairly unique う-Verb in Japanese in that it will only be used as a suffix. This is due to its meaning of 'to show signs of (A)', or 'to have the appearance of (A)'. It will be attached to nouns that the speaker experiences to be the case.
As めく itself is a verb, it may appear in several different conjugation forms depending on how it is describing the rest of the sentence. When connected directly to a second noun, the past-tense form めいた is most common.

• 昨日(きのう)までは嘘(うそ)みたいに暑(あつ)かったのに、やっと春(はる)めいてきた！
  It has been hot until yesterday, but it's finally starting to become spring-like!
• 冗談(じょうだん)めいて言(い)ったが、多分(たぶん)冗談(じょうだん)だったということは気(き)づいていないと思(おも)う。
  I said it like a joke, but I don't think they understood it as a joke.
• 皮肉(ひにく)めいたことを言(い)ってしまって、相手(あいて)が黙(だま)り込(こ)んでしまった。
  I said something which sounded like sarcasm and the other person fell silent.
• 彼女(かのじょ)はなんか謎(なぞ)めいた雰囲気(ふんいき)があるよね。
  She has a somewhat mysterious vibe, doesn't she?

This 'that the speaker experiences to be the case' part is important, as めく will almost always highlight the speaker's own personal feelings in regard to (A), and how they perceive it. The thing being described as (A) will usually not actually be (A), and the speaker is often aware of this fact.
