-	Ρρ Rho	+	'''Rho''' (uppercase '''Ρ''', lowercase '''ρ''' or '''ϱ'''; ˈroʊ) is the 17th letter of the [[Greek alphabet]]. In the system of [[Greek numerals]], it has a value of 100. It is derived from [[Semitic]] [[resh]] "head". Its uppercase form is not to be confused with the [[Latin alphabet\|Latin]] letter [[P]], although both are typeset using the same [[glyph]].

		+	== Uses ==
		+
		+	===Greek===
		+	Rho is classed as a [[liquid consonant]] (together with [[lambda (letter)\|lambda]] and sometimes the nasals [[mu (letter)\|mu]] and [[nu (letter)\|nu]]), which has important implications for [[morphology (linguistics)\|morphology]]. In both [[Ancient Greek\|Ancient]] and [[Modern Greek]], it represents a [[alveolar trill\|trilled]] or [[alveolar flap\|tapped r]].
		+
		+	In [[polytonic orthography]] a rho at the beginning of a word is written with a [[rough breathing]] (equivalent to ''h'') — ῥ ''rh'' — and a [[gemination\|double]] rho within a word is written with a [[smooth breathing]] over the first rho and a rough breathing over the second — ῤῥ ''rrh'' — apparently reflecting an [[aspiration\|aspirated]] or [[voiceless]] pronunciation in [[Ancient Greek]], hence the various Greek-derived English words which start with ''rh'' or contain ''rrh''.
		+
		+	The name of the letter is written in Greek as ῥῶ (polytonic) or ρω/[[wikt:ρο\|ρο]] (monotonic).
		+
		+	===Other alphabets===
		+	Letters that arose from rho include Roman [[R]] and Cyrillic [[Er (Cyrillic)\|Er]] (Р).
		+
		+	=== Math and science ===
		+	The characters '''Ρ''', '''ρ''' and '''ϱ''' are also used outside its Greek alphabetical context in [[science]] and [[mathematics]].
		+
		+	*In [[physics]] to represent:
		+	**[[Density]] (ρ)
		+	**[[Resistivity]] (ρ)
		+	**[[Charge density]] (ρ)
		+	**[[Rho meson]] (ρ<sup>+</sup>, ρ<sup>-</sup>, ρ<sup>0</sup>)
		+
		+	*In [[mathematics]] to represent:
		+	**The [[radius]] in the [[spherical coordinate system]]
		+	**The [[correlation coefficient]] of a population parameter
		+	**The [[spectral radius]] of a matrix <math>A</math> denoted as <math>\rho(A)</math>
		+	**The [[plastic number]]
		+
		+	*In [[economics]] to represent the discount rate of future pence cash flows
		+
		+	*In [[molecular biology]] to represent the Rho protein responsible for termination of RNA synthesis. In such occasions, it is often represented as {{unicode\|ϱ}} ("rho symbol" U+03F1), to avoid confusion with the Latin letter ''p''
		+
		+	*In [[ecology]] to represent the population damping ratio where ρ = λ1 / \|λ2\|.
		+
		+	*In [[programming]]
		+	**For [[LaTeX]], the symbols are <code>P</code> (Ρ), <code>\rho</code> (<math>\rho</math>), and <code>\varrho</code> (<math>\varrho</math>)
		+	**The lower-case rho ''ρ'' has a special meaning in the [[APL programming language]]
		+
		+	*In [[statistics]] to represent [[Spearman's rank correlation coefficient]], commonly known as Spearman's rho
		+
		+	*In [[Options]] theory to represent the rate of change of a portfolio with respect to [[interest rates]]
		+
		+	===Labarum===
		+	When rho is fused within a single typespace with the Greek letter [[Chi (letter)\|Chi]], it forms the [[labarum]], which is used to represent [[Jesus Christ]].
		+
		+	===Rhodes Scholars===
		+	Former [[Rhodes Scholar]]s are entitled to use the Greek letter rho as a designation of their status. When used, the symbol should precede the name.<sup>[]</sup>
