Question: (CNN) -- Five-time winner Roger Federer opened his U.S. Open account Monday with a straight sets win over Santiago Giraldo in New York.

Despite surrendering his serve three times, the 30-year-old Swiss enjoyed a relatively comfortable match against the Colombian, ranked 54 in the world, winning 6-4 6-3 6-2 on the Arthur Ashe Stadium court.

Leading 5-1 in the opening set, a number of uncharacteristic errors from Federer saw him squander a double-break advantage before he finally rallied to win 6-4.

The second and third sets were more straight-forward, though the world number three will be concerned about his winners-to-unforced errors ratio -- he finished with 36 winners and 35 unforced errors.

"It was quite up and down, getting used to the conditions," admitted Federer, in quotes carried by usopen.org.

"I don't think I've ever played my best in the first round but it's important to come through them and come up with a good feeling."

Home favorite Mardy Fish was ruthlessly efficient as he easily dispatched Germany's Tobias Kamke 6-2 6-2 6-1.

However fellow American Ryan Harrison was not so fortunate. The 19-year old lost out to big-serving Croat Marin Cilic, 6-2, 7-5, 7-6 (8/6).

Seventh seed Gael Monfils ruined the U.S. Open debut of Grigor Dimitrov of Bulgaria with a battling 7-6, 6-3, 6-4 victory, while Czech Tomas Berdych, the number nine seed, beat French qualifier Romain Jouan 6-2, 7-6 (7/4), 6-1.

Elsewhere, French 13th seed Richard Gasquet trounced Ukrainian Sergiy Stakhovsky 6-4 6-4 6-0, Serbian Janko Tipsarevic ousted France's Augustin Gensse 6-2 7-5 6-0, while Czech Radek Stepanek beat Germany's Philipp Kohlschreiber 6-4 6-1 6-3. 1. What sport are they playing?

Question: Approximants are speech sounds that involve the articulators approaching each other but not narrowly enough nor with enough articulatory precision to create turbulent airflow. Therefore, approximants fall between fricatives, which do produce a turbulent airstream, and vowels, which produce no turbulence. This class of sounds includes lateral approximants like (as in "less"), non-lateral approximants like (as in "rest"), and semivowels like and (as in "yes" and "west", respectively).

Before Peter Ladefoged coined the term "approximant" in the 1960s, the term "frictionless continuant" referred to non-lateral approximants.

Some approximants resemble vowels in acoustic and articulatory properties and the terms "semivowel" and "glide" are often used for these non-syllabic vowel-like segments. The correlation between semivowels and vowels is strong enough that cross-language differences between semivowels correspond with the differences between their related vowels.

Vowels and their corresponding semivowels alternate in many languages depending on the phonological environment, or for grammatical reasons, as is the case with Indo-European ablaut. Similarly, languages often avoid configurations where a semivowel precedes its corresponding vowel. A number of phoneticians distinguish between semivowels and approximants by their location in a syllable. Although he uses the terms interchangeably, remarks that, for example, the final glides of English "par" and "buy" differ from French "par" ('through') and "baille" ('tub') in that, in the latter pair, the approximants appear in the syllable coda, whereas, in the former, they appear in the syllable nucleus. This means that opaque (if not minimal) contrasts can occur in languages like Italian (with the i-like sound of "piede" 'foot', appearing in the nucleus: , and that of "piano" 'slow', appearing in the syllable onset: ) and Spanish (with a near minimal pair being "abyecto" 'abject' and "abierto" 'opened'). 1.
